Scott Duff asked:
How do we get at the eigenstates of a superposition?
We obviously need another operator! <ducks>
Actually, I think we need a universal method on scalars that
gives the eigenstates of that value. It might be C<$val.eigenstates>
or maybe just C<$val.states>. The method would work on non-superimposed
values as well, in which cases it would just return a list containing
the value itself.

Yes, but this:
if ($x | $y | $z == 7).states == 1 {...}
aren't nearly as nice as this:
if $x ^ $y ^ $z == 7 {...}
which means everyone will probably write:
if none($x,$y,$z) == 7 {...}
which is probably the right solution anyway ;-)
