Re: Now, what would you expect that loop to return, if it were like a map? You can't skip or restart map in the same way, you realise, probably because it could cause some very strange behavior.

I got it: You have next, last, continue to modify the looping. How about a keyword result or somesuch that is like the "return" from a function? Just give an argument to next, continue, etc. and you don't need new keywords.

Dropping off the end of the block is an implicit "continue", just as the last statement in a function is an implicit "return". If you don't give an argument to the next, last, or whatnot, it becomes an undef empty list and doesn't add anything to the result list.
