Removed most of the detailed examples about handing panics
from the go spec since it's now covered by Effective Go.

This change makes it legal to pass a struct value as receiver
outside the package declaring the struct even if the respective
struct type has non-exported fields.
This is a backwards-compatible language change motivated by the
fact that it is already possible to circumvent the assignment
restriction when calling methods through interfaces (see issue
1402).

Prior to this CL, there were two requirements about the
package name main.
1. The package that sits at the root of the import graph
(the one where program execution begins)
must be named main.
2. No other package in the program can be named main.
This CL only removes requirement #2, which can be done
without changing any other Go documentation.
The new wording and formatting is such that removing
requirement #1 can be done by deleting a single line,
but making that change is explicitly outside the scope
of this CL, because it would require changes to other
documentation at the same time.

These are syntactical changes to better reflect the communication
operator's new status in the language.
- sending to a channel is now done via a send statement
- there is no binary communication operation anymore which
leads to a reduction of the number of precedence levels
from 6 to 5 (yeah!)
- small semantic change: since a send operation is not part
of the expression syntax anymore, a <- send operator is
binding weaker than any other operator now
- receiving from a channel is done as before via the unary
receive expression
- communication clauses in select statement now can contain
send statements or receive expressions

Close of closed channel panics.
Receive from closed channel never panics,

The default float type is not very useful but for the most basic applications.
For instance, as it is now, using the math package requires conversions for float
variables (the arguments for math functions are usually float64). Typical real
applications tend to specify the floating point precision required.
This proposal removes the predeclared types float and complex. Variable declarations
without type specification but with constant floating point or complex initializer
expressions will assume the type float64 or complex128 respectively.
The predeclared function cmplx is renamed to complex.

Regular expressions may now be used in conjuction with full text
search. Godoc will show the first 10000 occurences in the source
code and highlight the respective text segments.
- added new flag -testDir to specify a small directory for testing
(fast index creation; default = "")
- use new FormatText function to format text and Go source
code in HTML, supporting multiple kinds of text selections
simulatenously); this replaces the uses of go/printer
Stylers
- for now removed currently unused mechanism for identifier-
specific JS popups (will come back in some form once we
have type or other useful information)
- various typo fixes and minor cleanups throughout
Missing:
- indexing of non-.go files

An entirely mechanical change, with these exceptions:
- removed 'stub questions' that reference the other FAQs
- removed "Why doesn't Go run on Windows yet?" - out of date
I will follow this CL with another that updates many of the

Not a bug per-se, the issue is that the fmt.Sprintf method inside the
ByteSize.String() method ends up calling itself to generate the String
representation of the ByteSize value. Infinite loops are bad.

Background: The current spec is imprecise with respect to the parsing ambiguity
for composite literals: It says that the ambiguity arises when the TypeName form
of the LiteralType is used. The following code:
if (B) {} ...
is not using the TypeName form (but the parenthesized TypeName form) and thus
could be interpreted as:
if ((B){}) ...
instead of
if B {} ...
Both compilers and gofmt choose the latter interpretation. One could fix the
spec by making the clause regarding the parsing ambiguity more precise ("...using
the _possibly parenthesized_ TypeName form of the LiteralType..."). The alternative
(chosen here) is to simply disallow parenthesized literal types. Except for a single
test case (test/parentype.go) there appears to be no Go code under $GOROOT containing
parenthesized literal types. Furthermore, parentheses are never needed around a
literal type for correct parsing.
