He also proposed that the overload be called opPower.
I want to add to two small things to that post of mine:
http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D&article_id=95123
The name opPow() may be good enough instead of opPower().
And A^^3 may be faster than A*A*A when A isn't a simple number, so always
replacing the
power with mults may be bad.
It wont be on x86. Multiplication has a latency of around 4 cycles whether
int or float, so x*x*x will clock around 12 cycles.
Yeah, but what's the throughput? With multiple ALUs you can get several
multiplications fast, even though getting the first one incurs a latency.
