So is the goal for numba to actually handle arbitrary Python code with
correct semantics, i.e., it's actually a compiled implementation of
Python-the-language? (I feel like most of where Cython-the-language
differs from Python-the-language is that Cython adds extensions for
stuff where getting speed out of Python-the-language would just be too
hard. Dynamic type inference for numpy arrays is definitely a good
start, but you can't even, say, promote a Python integer to a C
integer without changing semantics...)

Totally agreed on this point, the workflow for Cython could definitely
be smoother.
