A shotgun brainstorming of possible operator names:
well, I didn't follow this thread very closely (and I don't know if it is "officially" closed :-) but I suddenly thought about "yes". what about:
$x = not $a or $b; # vs $x = yes $a or $b;
$yesno = yes any(@foo) == any(@bar);
may not be gramatically correct English, but isn't it intuitive enough?
cheers, Aldo
