In order for everyone to air an informed opinion, a related question
is: will loop fusion be allowed with function calls?
Loop fusion currently only works with operators, and adding ^^ would
allow:
a[] = b[] ^^ 3;
But with pow you can't do that:
a[] = pow(b[], 3);

P.S. FWIW, I'm ambivalent on the issue; if functions were allowed for
automatic loop fusion that would tilt my opinion in disfavor of ^^,
and if not, it would tilt my opinion in favor of ^^.
I don't think this is a valid argument for making pow() an operator,
because what about sin()? cos()? It's all the same issue, and they all
can't be operators.
It's another case where pow(x, 2) is not the same as x ^^ 2.
The argument for excluding exponentiation is largely, "pow does the same
thing, without introducing an operator".
