Hmm, well, if values are just single-element subsets, then:
my %set of 1;
my 1 %set;
And presumeably also
my %set of true;
my true %set;
But the real question is: "Does the storage optimization
fall out naturally or does it need explicit instanciation
of a generic hash container for the unit type?"
