They can be declared to be arbitrary:
my %hash is shape(Any);

That's an interesting question. Some people would want them to, and
some people would definitely not want them to. I think the general
consensus is that people would not want them to be different, since in
the rest of perl, 2 and "2" are the same.
The object model that I'm working on actually identifies 2 and "2" as
the same object, indistinguishable in every respect. But that hasn't
been accepted (or even proposed)... yet.
