Clue me? How do I disassemble a proc in 1.9?
>> p = proc { |n| n + 2 }
=> #<Proc:0x3be994@(irb):1>
>> VM::InstructionSequence.disassemble p
>> class Temp1; end
>> Temp1.send :define_method, :m, p
=> #<Proc:0x3be9e4@(irb):1 (lambda)>
>> VM::InstructionSequence.disassemble(Temp1.instance_method :m)
=> nil
>> VM::InstructionSequence.disassemble(Temp1.new.method(:m))
=> nil
>> class Temp2; def m; 1 + 2; end; end
=> nil
>> puts VM::InstructionSequence.disassemble(Temp2.instance_method(:m))
== disasm: <ISeq:x@(irb)>===============================================

Maybe [1] would help? [1] http://groups.google.com/group/ruby-core-google/browse_thread/thread/932c0ea1078e294a Thanks for your work on this stuff! Wish it were easier for 1.9, but we do what we can :) -=R
I also wonder if ludicrous has any insight into this. How is it able to translate 1.9 to libjit, for example.
