The type checker does not currently report the set of pairs of
types that are tested for assignability (though gri and I
agree that it should). This information is useful for many
applications. For example, refactoring tool needs to know the
minimal set of interface satisfaction constraints that must be
preserved during a refactoring.
This package is a stopgap measure to deduce the same
information using another pass. Unlike go/types, it is not
robust against inputs containing type errors.

The Uses, Defs and Scope information provided by go/types is
inadequate for answering "what if?" queries about the
structure of the lexical environment.
In this code, for example,
var x int
func f() {
print(x)
x := ""
print(x)
}
the two referring Idents x appear at the same lexical depth,
inside the function f's Scope object, yet they resolve to
different objects.
This package associates a lexical.Environment instance with
every reference to capture these differences. Each
environment is a linked list of enclosing Blocks, and for each
block, a number indicating what prefix of its bindings are
visible. (Zero for the first 'x' reference above, 1 for the
second.)
+ Smoke test over stdlib.
This functionality could be integrated with the type checker
in lieu of the not-so-useful types.Info.Scopes data, at little
extra cost in code or in running time/space. We should talk
about that.

Nodes in a strongly connected component (which includes most

Previously type errors were reported via the web interface but
not logged, but this led to confusion as to why SSA

Today I learned that getElementByClass returns an
HTMLContainer, not an array, so the for loop was iterating its
properties, which include:
- the methods of the type, which were filtered out by the condition;
- the array-like integer indices of the elements, which we want;
- the ids of the same elements (!), which we weren't expecting.
The net result is that various functions were called twice,
causing the tree to be double-populated and clicks to cause
and expand+collapse.
It's a miracle to me that any JS program even approximately works.

The needMethods cache logic was wrong: it would treat any
previous call as a cache hit, even if 'skip' was true for that
call. As a result it could fail to generate methods for some
'skip' types, i.e. anonymous structs.

To avoid breaking URLs, we redirect /src/pkg/* to /src/*.
The URL /pkg is now the "directory" /src, which triggers the
"Packages" index.
All other references to "src/pkg" are now gone,
except a number in the namespace documentation which are
probably still illustrative.
Tested: go test cmd/godoc godoc

This function has been copied at least 6 times throughout
go.tools. This implementation is superior since it does
all I/O through the virtualized go/build file system, and it
is highly parallel (and much faster).
We expose two flavours, simple (for existing tests) and
parallel (for high-performance tools such as gorename).
This CL creates the go/buildutil package, which is intended for
utilities related to go/build.

Improve the generated code by using a const instead of a var for the names string.
This requires some refactoring to get neat const() and var() blocks.
Also change the generate map code go use a single sliced string, to reduce the
size of the compiled representation (only one string value).

Creating a new disk is the major latency cost of creating a
new instance. If we reuse a previous disk image, the VM and
CoreOS boot much quicker and start building again.
So add a mode where we don't mark the disk as delete-on-death
when we create it, and we search for a suitably-named existing
one on creation and try to reuse it.
It's a cache, essentially. It's still stateless.
