You could also use => to effectively qw all the list members. (I use keywords here to show that there's no roulette being played. They're interpreted as strings.)

do_something($_) for (
  exit => # comment
  sub =>
  exec =>
  do_something => # It's a string here, not a sub call!
);

sub do_something {
  print "Got ($_[0])\n";
}

Keep in mind that qw and => have somewhat different rules about what they quote: qw effectively quotes each run of non-whitespace; => quotes only runs of "word" (alpha-num-underscore) characters, and interprets everything else.
