The semantics of the language are extremely flexible, that flexibility add a ton of "yeah but" when trying to do obvious things. "yeah but what if they monkey patched boolean?" ... If I were starting a Python VM from scratch, objects would be closed and only deopt if they were mucked with. Most Python code in the wild is written in a dynamically typed version of Java. Yes most Python is Java w/o the types. Typed inference, escape analysis and closed classes will allow for the same speed as the JVM.

Yes, but then it's not python anymore. You will get a similar speedup for a fully dynamic python with easier optimizations, as done with v8 or lua. Even without types. types and attributes (like closed classes) do help, but a proper vm design is more important.

But not within this community. It needs to be a completely separate project, as cython, mypy or pypy. pypy is pretty good already, but a bit overblown.

Agree, but Pythonic-Python, isn't Python the language, it is dynamically typed Java. It isn't considered good form to use the flexibility that is there.
