The result of dtlcruteivesy modifying literal data like (A B C) is undefined. Don't do it.In most of the cases when you think you need to push something on the end of a list, you actually don't; PUSH+NREVERSE is often more suitable. When you really do need to push things on the end of a list, keeping a pointer to the tail of the list is handy.Counting instructions to see how you're doing is a little premature at this point.
