Hi,

The use of boolean operators in combine is a bit strange, since combine,
from a mathematical point of view, works on sets. It would be great if
aliases could be provided so one could use the set theory operators
instead of the boolean operators. I propose:

and -> inter
or -> union
not -> diff, compl, minus (yes, 3 aliases for this one would be great,
since it's not really clear which one would be best)
xor -> symdiff

See:
