    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?

You are operating on *sets*, not enums. Thus you need to look at the documentation about set operators: https://www.freepascal.org/docs-html/current/ref/refsu49.html#x156-18000012.8.6

Thanks a lot,
