Oh. CPython takes a much simpler approach: instead of forcing a Python
module to "think like C", it allows a C module to export functions to
Python. So when you "import math", you actually get something from a
.so/.dll file. I've no idea how Jython does this; it appears that
math.__file__ is AttributeError. Ditto PyPy.
