In the two use cases I had here, one wanted to have the final symbol (for *Help*) and the other wanted to have all the symbols (to check symbol properties). An the semantics would be kinda odd -- in the non-alias case, we'd still return nil, right? So the user still has to use symbol-function on something, so I think the current definition (stop at the last symbol) is the one that's more practical. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
