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);
