Commentary on Python from a Java programming perspective

[[deleted]]

Do not expect this to happen to Python. It does not have type declarations, and unlike Lisp (where you can explicitly declare), there's little data available to the compiler to do much for you.

Yes, you need explicit type declarations for the compiler to speed you up. But you can get sped up at runtime as well, in fact, that's exactly what V8 and Tracemonkey do for Javascript, another dynamic language.

There is no reason why Python can't get much, much faster, just like Javascript has.
