I don't see why not. It could behave the same as KVC,
which works both with scalars and NSValues. The only
situation I can think of where it would create trouble
is one where you have a method that takes an integer
argument that is supposed to represent the address of
an NSValue object -- I'd say that is decidedly an edge
case.
