Hmmm .. but that must have the type of r, so if you had
a 'multi-label' solution this would be quite nice, since
it would help constrain the type of r.

In a whole program analyser this would always be enough:
if there is any doubt due to some unused fields, then those
fields would just be dropped since they're not used .. :)

[Felix will do this for classes, not so much by design
as because that's how the instantiator works ..]
