It's a bit amazing how much variation in notation and even naming there
is for this. Other names for 'and' I've seen are 'et' and 'conjunction'
and for 'or' there's 'vel' and 'disjunction' and 'alternative'. There's
apparently also a convention of using dots on both sides of binary
operators to indicate precedence: "a :&: b .|. c" would be equivalent to
"a & (b | c)".

For arithmetic there's far less variation, probably because the
conventions are much older.
