Method calls often return just QVariant because we cannot be sure that
the method hasn't been shadowed. In order to figure out the right lookup
we should look at the type the type propagator assumed as the base of
the lookup. If the type propagator was assuming a list-length lookup we
need to try and generate a list-length lookup. If the base turns out to
be a QVariant after shadow-checking, the code generation will cleanly
fail (and refrain from generating bad code).
