I wonder if there is any rounding error going on with these pow, but
yes, even better this way.

sin is a library function, it has no special rights your own function
doesn't as far as I know.
I'd say, put an if(__ctfe) in sin:
if (__ctfe)
{
pragma(msg, "Yep, CT");
return 2.0;
}
else
{
// standard sin code
}
And tell us the result :)
