Understandably so.  Perhaps "(u)" and "(n)" would be better ASCII
equivalents for the union and intersection operators...

Hmm, I think using the dualism between set operations and
boolean operations is a good thing. Note that there is an
isomorphism between &&, || and ! for the logical side and
(&), (|) and (!) for sets---DeMorgan etc. We could even
introduce low precedence versions (and), (or) and (not).
Well, and of course (^) and (xor) corresponding to ^^ and
xor. They all form nice mnemonics for each other.
