Replace (delq nil (mapcar ....)) with analogous (mapcan ...) forms; this is in non-dumped files, it was done previously in dumped files. 2. Replace (delq FOO (copy-sequence BAR)) with (remove* FOO BAR), where #'eq and #'eql are equivalent 3. Replace (delq FOO BAR) with (delete* FOO BAR), where FOO is not a non-fixnum number. Saves a little space in the dumped file (since the compiler macro adds :test #'eq to the delete* call if it's not clear that FOO is not a non-fixnum number).
