I'm not quite sure I understood your question, sorry. > Do you foresee any machine-dependent optimizations? In my personal case, I am not looking for optimizations in the generated bytecode. Let me give a very basic example. Say we have these two functions: def inc(x): x = x + 1 def dec(x): x = x - 1 Examining the compiled bytecodes for these two functions: >>> inc.func_code.co_code '|\x00\x00d\x01\x00\x17}\x00\x00d\x00\x00S' >>> dec.func_code.co_code '|\x00\x00d\x01\x00\x18}\x00\x00d\x00\x00S' Now suppose that I wanted to mess with inc, and have it behave like dec. For that, I would like to do something like this, for instance: >>> inc.func_code.co_code = '|\x00\x00d\x01\x00\x18}\x00\x00d\x00\x00S' Of course, as of this moment, I get a TypeError exception, because co_code is read-only. The thing I've been wondering is why _is_ it read-only? In what circumstances having write access to co_code would break the language or do some other nasty stuff?
