21:04:02semzQuestion about iterate: A (for VAR initially ... then ...) clause can't use PVAR from a (for PVAR previous VAR) clause in the THEN part because the clauses expand to (PROGN (SETQ PVAR VAR) (SETQ VAR ...)). Is this an undocumented gotcha or does it follow from some principle I have missed and I should have expected it?
