Ok, that's the catch that I turned off because it was too expensive
(basically turns every `.` into a funcall).
Off the top of my head, I can't think how to catch this without a
huge overhead (wish we had condition-bind!). Perhaps the best thing
to do for now is remove that test.
Unless someone else has a clever idea?
