If you think that "matching polymorphic types" is too vague, I'm
not sure there's much daylight between there and spelling it out
in full as this latest patch does.  "anyrange is the only problem"
might be a tenable viewpoint today, but once this patchset goes
in there's going to be much more scope for confusion about which
arguments potentially match a polymorphic result.
