I've already written RipperRubyParser which generates emulates
ruby_parser. I can send it to you if you're interested, even though it
might require some refactoring since I'm both a Sexp- and Ripper-noob.
However, because of this bug http://redmine.ruby-lang.org/issues/show/1939
it's not reliable enough. Currently RipperRubyParser doesn't handle
local variables properly, it just parses them as s(:call, nil, :name, s
(:arglist)). Could we please get local variables straight from Ripper?

You would also have to update Ruby2Ruby to support the new lambda-
syntax and that blocks can capture blocks.

This would also be a good time to clean up the AST even more to make
it easier in the future. We should probably still support the "old
format", at least for some time... What'd you think Ryan?
