aha! i k n e w there was a one-word term for that,
but i couldn't think of it. thanks.

well, i've certainly used ^ a heck of a lot for exponentiation,
and i sure don't want to change now. but in the interests
of standardization and consistency (in the general sense, not
the technical tuning sense), since ** is unique for exponentiation,
then maybe we should adopt this separation.

^ for wedge product
** for exponentiation

should we create a poll? any other opinions on it?

let's keep ^ for exponentiation and use
/\ for wedge product

Yuck! I've got my Python library to overload ^ for wedge products. As **
is already exponentiation there's no conflict. And as ** for
exponentiation goes right back to Fortran, it's not like we're breaking
any standards anyway. I don't know of any languages that can overload /\.

how about the english language? i thought that's what we were talking
about.
