A little while ago I said I'd create a patch for ^^ as an
exponentiation. A couple of people had requested that I make a post to
the ng so they'd know when it happens. Here it is.
This is opPow(), x ^^ y

AWESOME! Thanks a lot, Don! I've been hoping for this since I started
using D.

I'm not trying to be rude, I'm just trying to illustrate that the first
point doesn't make a good case against an exponentiation operator. I can
only speak for myself, but I use exponentiation a lot. I mostly write
numerical code, and as I understand it, I'm not the only one in the
community doing so.
Being able to overload the exponentiation operator also makes a lot of
sense. Matrices and BigInts are the first things that come to mind.
