It seems that lerp can't give a sensible answer for integer inputs. It's new machinery, not the legacy C stuff extended with extra overloads.

I would prefer to fix this by explicitly annotating the functions that are supposed to get additional overloads because we keep getting this wrong, but we could also exempt lerp in 28.7.1 [cmath.syn] p2.
