Yeah, I've been following your proposal with interest. > It seems esp. relevant since pyviennacl seems to try to follow numpy > in many things *except* the definition of '*', and part of the hope is > that if this gets accepted into Python then it'll let us get rid of > such incompatibilities between projects.

You're right about the incompatibility, and it is deliberate: we did have some discussions about it when planning last year, and decided where it made sense to follow matrix semantics (since that's what we expect people to be using PyViennaCL for). But it is a mess! So you should fully expect PyViennaCL to adopt @, at which point I'll have * be used for elementwise operation. That ought only change the semantics of `vector * vector` (currently undefined) and `matrix * matrix`, off the top of my head.
