This is such a common "mistake", and really more of an annoyance, I wonder
if it might be better if pow were switched to a template that called the
actual pow after casting the first argument to real. Often times, one does
not use reals as their variable type, and I seem to recall this kind of
error happens even with literals for both arguments...
Something like:
real pow(T, U)(T t, U u)
{
return _pow(cast(real)t, u);
}
