But bytecode is like assembly - there is no tree-structure. A opcode is followed by a number of arguments, and oopcodes are in a seqence. However the bytecode is _generated_ from the AST somehow. Maybe you can work on that. Also take a look at psyco, it already does optimizations for numeric calculations. Besides: I serously doubt you can do much optimization on the bytecodelevel itself, as it is very highlevel. The optimization efforts like in psyco don't alter bytecode - they replace it....
