My understanding is that to DROP a compound stem frees all associated storage.
Freeing an individual variable or member of a compound does not. In fact, it
can be demonstrated that to DROP an individual member of a compound actually
*increases* the storage used.
Does RETURN from a PROCEDURE EXPOSE free storage of variables not
EXPOSEd? Can that be useful?
