[REBOL] Re: bitset help

This all brings up a really good point for me. Sometimes I'm so stuck on
certain things I can't see the obvious. How many of us have suffered with
AND, OR, and XOR in our code, stopping to think so hard about whether we had
the right operator in there, particularly when you have to distinguish
between bitwise and logical operations!
INTERSECT, UNION, and DIFFERENCE are so much more human friendly! Just
looking for quick definitions I find:
Intersect - To have points in common.
Union - The set, each of whose elements lies in at least one
member of the collection.
Difference (symmetric) - The set of elements that belong to one
but not both of two given sets; the union of their relative
complements; the relative complement of their intersection
in their union.
Carl S. probably just shakes his head sometimes when he sees how hard some
of us (OK, me) make things when he has made them so easy. Hopefully he'll be
patient as we unlearn things. :)
