I can understand that, but here as a potential industrial users of Numpy,
we can't really afford the risk. We're looking at Numpy as a key piece of
a Python replacement of commercial software for critical daily production.
If we build Numpy/Scipy into our system, it has to work. We don't want to
be anyone's beta testers.

The current SVN of numpy and the current SVN of scipy usually work with
each other (perhaps with only a day lag).

This is the plan and it is why we are being slow with getting 1.0 out.
But, we *need* people to try NumPy on their codes so that we can
determine whether or not API additions are needed. Without this testing
we are just guessing based on the developer's own codes which do not
cover the breadth.

We need some of these people to convert earlier than that, though, so we
can make sure that 1.0 really is ready for prime time. I think it's
very close already or the version number wouldn't be so high. We are
just waiting for more people to start using it and report any issues
that they have before going to 1.0 (I'd also like scalar math to be
implemented pre 1.0 as well in case that requires any C-API additions).
Thanks for the feedback. What you described will be the basic behavior
once 1.0 is released.
Note that right now the only changes that usually need to be made are a
re-compile. I know this can still be annoying when you have a deep
