Compiling a program is different than running it. A JIT compiler is a kind of compiler and it makes a compilation step. I am saying that Python is not a compiler and in order to implement JIT, it would have to change that fact. > of Python that uses .NET.

But still not the user's code, only the interpreter, which is running in assembly already anyway in CPython. -- http://mail.python.org/mailman/listinfo/python-list
