I can't, I am sorry, I don't remember the details anymore.
Feel free to ignore what I have written about Pyrex, lot of people
appreciate it, so it must be good enough, even if I was not smart/

In the past I have used some C for that purpose, but have you tried
the D language (used from Python with Pyd)? It's way better,
especially if you for example use libs similar to itertools functions,
etc :-)

Why not just write extension modules in C then?

Unladen swallow developers want to try everything (but black magic and
necromancy) to increase the speed of Cpython. So they will try to
compile up-front if/where they can (for example most regular
expressions are known a

CPython uses a C compiler
You can email these questions to the unladen-swallow mailing list.
They're very open to answering questions.

I am very excited by this project (as well as by pypy) and I read all
their plan, which looks quite practical and impressive.
But I must confess that I can't understand why LLVM is so great for
python and why it will make a difference.
AFAIK, LLVM is alot of things at the same time (a compiler
