[Parsetree] RCR for Parsetree

[Werner Schuster (murphee)]

howdy,

Hm... why_ talks about JRuby's NodeVisitor:
http://redhanded.hobix.com/inspect/visitorsWhoStealRubyOffToNewVms.html
and wonders if it would be useful to add as RCR.

Any thoughts on a RCR to add ParseTree (or a standard library in Ruby
that turns Ruby code -> ParseTree format) to the standard
lib/implementation?

It'd certainly make a lot of tools easier to write (since you could rely
on this to work on all Ruby versions) and would allow for things like
LISP-style Macros.
ParseTree is available now, but it still requires a compiler on the
users system - having it available as standard would be nice.

Thoughts?
