Actually the Perl version can be a bit more succinct:

  for (split /\s/, a b c d) {print elem = $_\n}

BTW does ruby let you do one-liners as in perl -e?

True. I consider $_ and friends to be ugliness best avoided, however. Perl
can be made plenty succinct, but usually at the cost of readability. To read
such perl code you need to keep a lot of syntax rules in your head.

Btw, the best place to learn about ruby is www.ruby-lang.org.
