last time '@' was considered as a new operator, that character had no uses in the language at all. Now it is the decorator marker.

The only alternatives left would seem to be ?, ! or $, none of which look particularly multiplicationish.

But would it be totally outlandish to propose A**B for matrix multiplication? I can't think of what "matrix exponentiation" would mean...

But ** has the same problem -- it already represents an elementwise operation on numpy arrays.
