Yes, when there's an error (an exception in python lingo) python prints out a
lot of details about what happened. Those details are critical for debugging

Mmmh, I'm pretty sure you can. I don't remember the details (rarely use
windows) but I know it's possible to cut/paste from a command window. Not as
nice as in unix, but possible.

Strange, I never saw your post there and I've been on the list for a while.

It depends on what you need. For numerical work it's fantastic. Just yesterday
on scipy-user Eric Jones (weave's developer) gave me an example on how to
access the raw data of a Numeric array through weave. After some more
discussion I posted his example (useful) at:
along with many other examples I've been collecting on how to use weave.
For wrapping large libraries, there's always Swig and Boost.Python.
And I'd suggest dropping the condescending tone. Weave and scipy are very
impressive pieces of work, put out there for free by bright, talented people.
If you know of a specific limitation, document it properly and it may be
addressed (if it falls within the problem domain of weave/scipy).
That kind of off-the-cuff comment ("I bet it can't handle complex...") isn't
going to get you very far when asking for help from the very people who wrote
it. Take it as friendly advice for the future. Those guys are good and
extremely helpful in general, I've experienced their dedication first hand.
