The name (and location) is of course endlessly bikesheddable :)

It might be good to even go a step further, and make it "amath" (or
"numbers.math", or ...), a type-agnostic math module.  Such a module
would likely be slower than math, cmath, or "dmath", but should end
the proliferation of math modules.
