They're overloaded up to the point of type inference, after which they
become integer operations. I think it's better not to have something
as inconsistent as SML.
This works:
- op +;
val it = fn : int * int -> int
- op + (1.0, 2.0);
val it = 3.0 : real
This doesn't:
- val myadd = op +;
val myadd = fn : int * int -> int
- myadd (1.0, 2.0);
