Today's update thusfar:
- singleton methods (def x.y and friends) are compiling now
- singleton classes (class << x) are compiling now
- fixed a bug in for loop compilation
- fixed a nasty bug where class/module bodies were damaging the
surrounding scope
This leaves the following features still not compiling:
argspush (foo(*x, y, z))
backref ($~ $+, $&, etc)
classvardecl (@@x = 1 within class body)
colon3 (defining constant as ::Foo)
flip (while (true)..(false) ...)
opelementasgn (a.[]=(...) in operator form)
optn
postexe (END {...})
rescue
retry
super
zsuper
and all non-local flow control (next, break, return, redo within blocks)
Short list!

More updates:
- class definitions are compiling
- module definitions are compiling
I keep stalling on rescue and non-local flow control, but they're coming.

Updates:
- case nodes are compiling for most normal cases; "when" with multiple
values doesn't compile just yet.
- valias and undef compile (trivial).
- for loops compile (basically just like calls to "each" with a
special no-scope block).

Here's a list of the AST nodes that do and don't compile currently.
We're looking pretty good so far; there's a short list of in-method
nodes that don't compile yet, and really only a couple really nasty
ones (case/when, rescue, maybe sclass/defs).
I think we're on target to have everything compiling by November.
That's my goal for the compiler.
Anyone who wants to dive into remaining nodes, be my guest.
