I must be too ignorant to see why STDOUT should be closed in a one-liner (???)

Anyway it's true is that chaining with and is a lazy way to avoid the already mentioned scalar comma operator:

  print, exit if cond

This seems to confuse many people, but has the same effect as

  do {print; exit} if cond
