You can still pull the code for a method using #source_location [though 
it's definitely not as nice as using parse tree was, and not as stable].

A crude example of extracting a method can be found in the method 
describer gem [1].

What problems are you running up against exactly?  Learning lessons from 
python decompyle might be helpful, too.
I also remember that Paul Brannan had some type of iseq -> c translator, 
that might be related.
GL!
