Yep. A key can (or should, at least) be an integer, a string, or a PMC.
Ints for by-offset lookup, strings for by-name lookup, and PMCs because
some things know what they should hash to or what their integer value is
better than we do. Or so they think, at least, and who am I to decide
otherwise? :)
