What for?  You'd ultimately have to depend on the various actual input
types' native equality operators, so I don't see what this'd buy except
a layer of useless-seeming overhead.  Also, it could only be hashable
if the input type's equality is hashable, and we don't have any way to
deal with a "sometimes hashable" equality operator.
