|Well yes... but our version uses more words, so it must be better ;-)

Are you saying the same thing?  Well, sorry.
I wanted to emphasize $_ assignment.

By the way, do you prefer the behavior like:

  str = $_.dup
  if str.chomp!
    $_ = str
  end

It may be better to incorporate with $_ usage.
But use of $_ is not recommended anyway though.
