[fpc-pascal] star operator on enum types

[Giuliano Colla]

I found in a fpc program a statement sort of:

Type
   TSomeType = (a,b,c)
   TaType = set of TSometype
var
   setA,setB: TaType;
.....
*if setA * setB = [] then doSomething*;

which I found very smart to detect if the two sets have some common 
elements, but I've been unable to find in the fpc documentation how the 
* operator is overloaded in fpc when dealing with enumerated and sets of 
enumerated types. Should I find out by trial and error or it's written 
somewhere?

Thanks,

Giuliano
