This is the problem that I've tried to describe:
All standard Python tools for ABI level access require C knowledge.

Against C. As I said, CFFI is good, but not enough to work conveniently with
binary interfaces, and the reason for that is that it is C-centric.
I support fijal - my position is that rewriting the same code in faster language
is not a way to solve performance problems. Language as a problem is a
failed smoke test for app architecture.

Fair point. Thanks for the feedback. Sometimes I feel like I should just stop
wasting my time on ideas, and start eating some pills so that I could better
concentrate on a mindless coding.
