I actually basically like PEP 225,
although I find @*, @+, etc more
readable, and to provide the right
visual emphasis. (Rather than ~*, ~+, etc.)

Additionally, I do not think Unicode addresses
the problem central to the PEP, as there is as
far as I know no standard symbolic distinction
between, say, elementwise multiplication and
matrix multiplication.  So I think the PEP is
basically needed (perhaps with @ instead of ~).

That said, what kind of problems do you have in mind?

Cheers,
