I would argue against allowing template parameters of floating-point
type, because you get two distinct functions instead of one because
of rounding errors: func<1.0> vs func<0.9999999999999>.
I have no objection to deprecating floating point static constants;
I just think we should follow our normal policy of issuing warnings first.

Agreed.
