It uses a bytecode representation internally, but doesn't currently 
write the bytecode to disk like python does.

The VM::InstructionSequence class gives some access to the bytecode. 
You can get the individual elements of the sequence by calling #to_a.

There is support in Nodewrap for saving/restoring instruction sequences, 
but needs to be updated for the latest 1.9.
