I see, so there's no requirement that functions that don't make sense
for non-arithmetic types should simple be disabled.
The context of the questions: right now, there's no way to directly
query any type if it's integer. (i.e. there's no is_integer in
type_traits).
I thought I could use numeric_limits::is_integer. But it looks like
I'll have to have a second layer, as I can only pass integral types
to is_integer.

Thanks,
