Re: [Psyco-devel] Psyco and log4py in the same module

[Alberto Di M. <Alb...@ce...>]

Hi Armin,

thanks for the suggestion. It works fine. And I must say the result is
pretty amazing. I had some code that was taking several minutes to complete
and with Psyco takes a few seconds. Incredible.

For the moment I can probably include a patched copy of traceback.py with my
code, but let me know if you manage to push a fix into Psyco.

Merci beaucoup!

Alberto
