Well I'll chime in here. I am currently working on an alternative that
I want to get ready by Python 1.7. The numpy code isn't UNmaintainable
--- but it is pretty involved. The difficulty is trying to make a
significant body of users happy.
The solution I'm working on is to make the NumPy Object a bonified Python
Class (my solution to the type/Class dichotomy is to make everything
classes). The addition of the buffer-type to Python makes this a workable
solution now. I'm projecting completion by the end of the summer. (But,
you know how dates get pushed...)
The NDArray class will still be fast due to carefully placed C-code that
will borrow from the current code-base. But, it should be considerably
easier to maintain and enhance (not to mention the advantage of
subclassability --- with C-extensions to NumPy not caring).
If anybody would like to help me. I can easily set up a CVS tree for
