That may be the core of the confusion here. Bytecode hacking is NOT
supported in standard Python. The language definition pretty much
stops at "function objects have a __code__ attribute that refers to
the immutable code object defining the algorithm they execute when
called". Anything below that point is implementation dependent (hence
the disclaimer on the output of the 'dis' module).
