Oh, I meant to say CPython (the default implementation of Python), not
Cython. I didn't realize that they were different projects.
So the method dispatch seems to be a great obstacle to an
object-oriented SIMD API. That would seem more feasible in C++ with
non-virtual methods. Java has final methods, which can be useful
information to the JIT. C# seems to have "sealed" methods.
Interestingly, the Mono.SIMD API uses static methods, which I guess is
to avoid the dispatch problem. But it makes the code look uglier. For
example, instead of a + b, you have to do Vector4f.Addition(a, b).
