Is it too late in this discussion to point out that, in non-perl
usage, eigenstates are associated with the operator, not with the

So asking for the eigenstates of a quantum superposition is asking the
wrong object for the property.
Probably is, yes :(. I argued the same thing a couple of years back
(http://dave.whipp.name/sw/perl6/perl6_xmas_2008.html -- wow, p6/rakudo
has advanced a lot since then!) when I suggested "bra-ket" notation for
extracting the "values of a junction":
$player_value = max |< 4..21 |==| $player_value_junc >|
(in this case, the value of a blackjack hand). Since then, I simplified
this idea to use a more perl6ish meta-operator:
$player_value = max 4..21 G== $player_value_junc
My current belief is that it is likely that there'll eventually be
sufficient "core" functionality that I'll be able to implement something
like this as a module. So I don't push it except when someone else
starts a thread about the "values of a junction" :).
