Right. Taking a slightly better look at the PCL walker, it seems to
ignore variables totally -- since they don't matter for the stuff
it is doing.

How painfull are the workarounds I suggested?

(While getting the PCL code-walker to add variable information to
environments doesn't seem horribly hard, it seems fiddly enough that
unless something makes it rather urgent, I doubt I'll get to it very
soon.)
