in reply to Understanding the map function

It makes perfect sense to me, though I would probably rephrase it thusly:

Evaluates the BLOCK or EXPR for each element of LIST (locally setting $_ to each element) and returns a list of the results .

That help any?

    Nitpick.

    ...returns a list value for each element of LIST...

    It took me a while to get my head 'round that. Once you do the docs make more sense.

      That would make it more confusing, to me. It already says 'evaluates something for each element in list', thus 'returns a list of the results' cant mean anything but 'list of evaluated somethings for each element in list' ... or not?

      That edit makes the definition imprecise. map can return multiple list values for each element of LIST.

    Thanks - I prefer your suggestion, which makes a clear overview from the beginning.

    Hmmm... though I wonder if anything makes sense provided you already know everything it is trying to say.
