I like that!
However, it is orthogonal to the additional operators question.
Some thoughts:
I do like the idea of having additional operators, but it seems that the
strongest use case is matrix operations. While the current matrix
implementation is clearly inadequate, we had a good discussion a while
back about how it could be improved, and maybe if we could find a way to
implement that well, we'd be OK. I always did find Matlab's "dot'
operators to be kind of annoying (though mostly because what I most
often need was the "dot" version)
I guess what I'm saying is that adding a bunch of operators just for a
few matrix operations may not be worth it.
If we can see substantial other uses, then it may be worth it -- are
there any?
An example is the PEP referenced above -- it would not be nearly as
strong if numpy were the only motivator -- I think the database example
is a very strong addition -- is there something similar for additional
operators?
