### 3223. `lerp` should not add the "sufficient additional overloads"

Discussion:

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.
