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.
