What are you talking about? See this:
[dalc...@trantor tmp]$ cat exc.pyx
def main():
try:
raise ValueError
except object, e:
pass
[dalc...@trantor tmp]$ python -c 'import pyximport;
pyximport.install(); import exc; exc.main()'
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "exc.pyx", line 3, in exc.main
(/u/dalcinl/.pyxbld/temp.linux-i686-2.6/pyrex/exc.c:430)
raise ValueError
ValueError

Yes, I understand that part.
