I've been using NumPy to do various problems in theoretical
astrophysics, without any problem. In my experience, I use the
NumPy-style element-wise array combinations more often than I use
actual matrix math. I don't mind having to write matrixmultiply the
few times I have to treat my 2D arrays as matrices.
This is clearly not your experience, but it may help you understand
why there isn't more of a groundswell of support in favor of
specializing NumPy more towards linear algebra.
Syntax helps, such as ' for transpose, will simply not happen, due to
python's general-purpose nature. Introducing new operators will also
likely not happen.
