Compiler produces different bytecodes, and allocates local variables on
stack (just like C) very fortunately, steps like that allowed Python to
drop moniker of "ridiculously slow language". And people should decide
what they really want - fast language which can stand against the
competition, or language with dynamicity and reflection capabilities
beyond any practical need. I make first choice any time. And then it
makes sense to just accept that any function can be JIT (or AOT)
compiled, and there's nothing to fish inside of it (but for the raw
machine code of unknown architecture).
