please add orEqual operator

[joe]

Isn't this what switch statements are for?  Perhaps a condensed operator
version of a switch would be useful?

    if (a == 0 : 1 : 2) {
    }

Or perhaps something similar to the set version, but without the set:

    if (a of 1, 2, 3, 4, 5, 6) {
    }

One could do this as a standard lib variadic function, I suppose:

    if (select(a, 1, 2, 3, 4, 5, 6)) {
    }


Cheers,
Joe
