[Cython] aritmetic with arrays in Cython

[Ian Henriksen]

Nice module! That seems to implement most of the basic functionality I've
seen lacking. Ideally, I'm still trying to find a way to be able to do
something syntactically like this:

cpdef whateverfunction(double[:] a, float[:] b):
    return a + a * b + .5

It would be ideal if that sort of thing were already a part of Cython. All
things considered though, most of what I'm looking for seems to be there.

Thanks!
