Using <> for opCmp

[Lionello Lunesu]

The operator < > <= >= all use opCmp, but if you want to differentiate 
between the three cases (< == >) you either have to call opCmp yourself 
or use multiple comparisons.

I'd like to suggest using the operator <> for an implicit call to opCmp, 
returning the actual comparison value (<0, 0, >0).

* <> is already valid and used (albeit for floats only ATM)
* if(x<>y) will work as supposed to without additional changes (in fact, 
it already does**)
* no explicit reference to the hidden function "opCmp"

L.

**It seems that <> already works, but it returns a boolean true/false, 
instead of an integer, so it currently is the same as !=.
