[pypy-dev] Compatibilidad with boost python

[Riccardo Rossi]

Dear Amaury,
         first of all thank you for your answer. I think i could hack the
boost to compile with a different python, however your last warning is
actuall the answer i was interested in getting.

if you tell me that the interface will be actually slower than in cpython,
than most probably it will not fit my needs.

i will keep monitoring your project (i really believe you do a very
interesting job) in the hope the link to C/C++ will get better (or that
boost_python will be ported based on cffi)

thank you
Riccardo
