I think this particular example would be a mistake, because that cast
would be lossy, so you want to invoke it only when the user explicitely
selects it. The other way around would be fine, I think, that is,
F(float)
F(float8)
and the call is F(int)

Well, if the other 9/10 were clear, there would be no discussion. The
problem is that the missing bits have not been designed and thus we
don't know if this 1/10 will be useful to them. We need to find a
complete design before committing to any initial portion which may turn
out to be bogus down the road.
