Unfortunately, no.

My 1.9 fixes were for SexpProcessor only. The intent is to get to the  
point where 1.9 and other non-ASTable implementations can  
automatically fall back to ruby_parser.

1.9 dropped support for storing AST information. ruby_parser can take  
over for some of that, but the biggie is procs... People who design  
DSLs on procs using ruby2ruby to do manipulation are going to be  
sorely disappointed in ruby 1.9. Unfortunately I don't have a solution  
at this time. There has been some talk about a bytecode decompiler for  
procs, but I don't even know if it is feasible at this point.
