9346c6d901 make every func literal expression allocate, 
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)

b85147cd70 change the encoding of uints to simplify overflow checking and to make them 
easier and faster to read.  they are now either a one-byte value or a n-byte value
preceded by a byte holding -n.

2210a643b7 Intersperse comments nicely when printing an AST. 
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.

6d3d25de21 Ring ADT. 
- 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.

052a66babd runtime: fix init scheduling bug. 
if there is a goroutine waiting to run
and the init goroutine enters a system call,
entersyscall was trying to kick off a new
scheduler for the other goroutine, causing

3d42e691b9 make 6l produce dynamically linked binaries (although they are fully statically linked as far 
as go is concerned).  the -d flag is now flipped; as on the mac, -d disables dynamic.

much remains to be improved to move the output closer to the gcc format.
