- more orthogonal functionality of filter functions for better re-use
go/doc/doc.go:
- simplified interface
- collect filenames of packages so that they can be shown
godoc:
- removed TODO, show list of package (linked) files used to create documentation

Return checking is now done as a general flow check at the end
of function compilation, since break and goto complicated the
way I was doing return checking before. Goto-over-declaration
checking is also done as a final flow check.
Temporary variables used for effect extraction are now
actually temporary. Otherwise "op=", "++", and "--" appear as
declarations that cannot be jumped over.

- Changed filter function for parser.ParsePackage to
take an *os.Dir instead of a filename for more
powerful filters
- Removed TODO in ast.PackageInterface: Now collect
package comments from all package files
- Cleanups in godoc: Use the new ParsePackage and
PackageInterface functions; as a result computing
package information is much simpler now.

single frame and non-overlapping variables reuse frame slots.
As a result, entering and exiting blocks no longer requires
code execution, which means jumps across block boundaries
should be doable now. Frame slot initialization happens at
definition time now, instead of at frame creation time. As an
added bonus, Scope's are now exclusively compile-time objects
and we no longer need to specially track the function
activation frame for access to out vars.

so that == on func means that the
functions originated in the same
execution of a func literal or definition.
before, there was an inconsistency:
func() {x++} != func() {x++}
but
func() {} == func() {}
this CL makes the second case != too,
just like
make(map[int]int) != make(map[int]int)

gofmt formatted source code looks pretty good already;
with a bit more fine-tuning it should be great.
printer.go:
- Implemented comment intersperse algorithm.
The approach is a result of many trial-and-error
experiments but at this point reasonably simple
and open to arbitrary fine-tuning.
parser.go:
- Simplified handling of lead and line comments
(formerly called leading and trailing comments).
- Use a comments list instead of an array (I may
change this back - this is not obviously better
and uses more space).
doc.go:
- Remove comments from AST nodes that have been
'consumed' in the documentation to avoid duplicate
printing of them. Allows for better control of
what is printed w/o use of printing control flags
(which are hard to use and not fine-grained enough).
Corresponding adjustments to various clients of these
files.

- Provides analogous functionality to a doubly-linked list
implementation.
- Completely symmetric set of operations.
- Operations on the ADT do not lead to results that are
outside the domain of the ADT (closed interface).
- Alternative to container/list.

and decrement. blockCompilers now form a tree the mimics the
nesting of scopes and provide convenient ways to enter and
exit scopes. blockCompilers also track the break and continue
PC for the current block. The statement testing interface now
works in lists of statements, which simplifies a bunch of
things.

unpacking for assignments, call arguments, and returns. This
change revamps the whole assignment compilation system to be
multi-valued, using the new MultiType type and multiV value.
Function calls, returns, and assignments now share a lot of
code and produce very consistent error messages.
