Ah, DMD cheats here - I didn't see neither the INLINE_Y2LX path, nor the fact that DMD apparently executes the fy2lx instruction at compile time for you.

That's worrying.
Either way, this is the most basic non-linear maths. We really really do need
this accessible in CTFE. Especially considering x^^y is an operator!
