The new break and continue actions do not work in html/template, and
fixing them requires thinking about security issues that seem too
tricky at this stage of the release. We will try again for 1.11.
Original CL description:
text/template: add break, continue actions in ranges
Adds the two range control actions "break" and "continue". They act the
same as the Go keywords break and continue, but are simplified in that
only the innermost range statement can be broken out of or continued.

The EBNF production
Function = Signature FunctionBody .
was used in FunctionDecl, MethodDecl, and FunctionLit, but only
for the latter it shortened the syntax slightly.
This change "inlines" Function which simplifies FunctionDecl and
MethodDecl and gets rid of the Function production.
This has no impact on the specified language. Also, the Function
production is never referred to by the prose, so it's safe to
remove it from the spec.
Finally, neither go/ast nor go/parser have a representation of
this production via a corresponding node or parse function, so
no possibly valuable documentation is lost, either.

When we introduced the notion of alias type declarations, we renamed
"named type" to "defined type" to avoid confusion with types denoted
by aliases and thus are also types with names, or "named types".
Some of the old uses of "named types" remained; this change removes
them.
Now the spec consistently uses the terms:
- "defined type" for a type declared via a type definition
- "type name" for any name denoting an (alias or defined) type
- "alias" for a type name declared in an alias declaration
New prose is encouraged to avoid the term "named type" to counter-
act further confusion.

A method expression is of the form T.m where T is a type and m
is a method of that type. The spec restricted T essentially to
a type name. Both cmd/compile and go/types accepted any type
syntactically, and a method expression was really just a form
of a selector expression x.f where x denotes a type.
This CL removes the spec syntax restriction from MethodExpr
to match the actual implementation. It also moves MethodExpr
from Operand to PrimaryExpr, because that's what it is.
It still keeps the separate notion of MethodExpr even though
it looks just like a selector expresion, since a MethodExpr
must start with a type rather than a value, and the spec's
syntax expresses this bit of semantics via distinct productions
(e.g., conversions look like calls but also must start with
a type).

Throughout the spec we use the notion of a constant x being
representable by a value of type T. While intuitively clear,
at least for floating-point and complex constants types, the
concept was not well-defined. In the section on Conversions
there was an extra rule for floating-point types only and it
missed the case of floating-point values overflowing to an
infinity after rounding.
Since the concept is important to Go, and a compiler most
certainly will have a function to test "representability",
it seems warranted to define the term explicitly in the spec.
This change introduces a new entry "Representability" under
the section on "Properties of types and values", and defines
the term explicitly, together with examples.
The phrase used is "representable by" rather than "representable as"
because the former use is prevalent in the spec.
Additionally, it clarifies that a floating-point constant
that overflows to an infinity after rounding is never
representable by a value of a floating-point type, even though
infinities are valid values of IEEE floating point types.
This is required because there are not infinite value constants
in the language (like there is also no -0.0) and representability
also matters for constant conversions. This is not a language
change, and type-checkers have been following this rule before.
The change also introduces links throughout the spec to the new
section as appropriate and removes duplicate text and examples
elsewhere (Constants and Conversions sections), leading to
simplifications in the relevant paragraphs.

For non-constant shifts with an untyped constant shift count, the
spec only said that it must "be converted to unsigned integer type".
go/types accepts any (arbitrarily large) integer value. Both cmd/compile
and gccgo require that the shift count be representable as a uint value
in that case (if the shift count is typed, it may be any unsigned integer
type).
This change adjusts the spec to state what the compilers have been doing
all along. The new wording matches similar rules elsewhere (e.g., for
untyped array and slice indices). Also, while technically this is a
restriction (we could permit arbitrarily large shift counts), in practice
this is irrelevant.

This change removes the punitive language and anonymous reporting mechanism
from the Code of Conduct document. Read on for the rationale.
More than a year has passed since the Go Code of Conduct was introduced.
In that time, there have been a small number (<30) of reports to the Working Group.
Some reports we handled well, with positive outcomes for all involved.
A few reports we handled badly, resulting in hurt feelings and a bad
experience for all involved.
On reflection, the reports that had positive outcomes were ones where the
Working Group took the role of advisor/facilitator, listening to complaints and
providing suggestions and advice to the parties involved.
The reports that had negative outcomes were ones where the subject of the
report felt threatened by the Working Group and Code of Conduct.
After some discussion among the Working Group, we saw that we are most
effective as facilitators, rather than disciplinarians. The various Go spaces
already have moderators; this change to the CoC acknowledges their authority
and places the group in a purely advisory role. If an incident is
reported to the group we may provide information to or make a
suggestion the moderators, but the Working Group need not (and should not) have
any authority to take disciplinary action.
In short, we want it to be clear that the Working Group are here to help
resolve conflict, period.
The second change made here is the removal of the anonymous reporting mechanism.
To date, the quality of anonymous reports has been low, and with no way to
reach out to the reporter for more information there is often very little we
can do in response. Removing this one-way reporting mechanism strengthens the
message that the Working Group are here to facilitate a constructive dialogue.

To avoid confusion caused by the term "named type" (which now just
means a type with a name, but formerly meant a type declared with
a non-alias type declaration), a type declaration now comes in two
forms: alias declarations and type definitions. Both declare a type
name, but type definitions also define new types.
Replace the use of "named type" with "defined type" elsewhere in
the spec.

First steps towards defining type aliases in the spec.
This is a nomenclature clarification, not a language change.
The spec used all three terms 'embedded type', 'anonymous field',
and 'embedded field'. Users where using the terms inconsistently.
The notion of an 'anonymous' field was always misleading since they
always had a de-facto name. With type aliases that name becomes even
more important because we may have different names for the same type.
Use the term 'embedded field' consistently and remove competing
terminology.

have a body (except maybe DELETE), but it's late in the Go 1.8 release
cycle and I want to do the proper fix.
The proper fix will look like what we did for http2 and only retrying
the request if Request.GetBody is defined, and then creating a new request
