It also says:
The situation gets worse when you need to extend the import
mechanism from C: it's currently impossible, apart from hacking
Python's import.c or reimplementing much of import.c from scratch.
OTOH, it's not obvious to me why this should be so. Can't I
access/replace builtins.__import__ from C/C++?
That said, if I could do that, it doesn't seem like much trouble at
all to get the behavior I want.
