Actually, no :-)
disjunction: any()
conjunction: all()
abjunction: one()
injunction: none()
So an abjunction is a junction requiring that exactly one of its
elements match. I don't see much use for it, but I haven't worked
with Perl 6 junctions in practice yet. It'll probably come in handy
about as often as logical xor does.
