Disagree that mine has a double-negative.

Perhaps a matter of interpretation here. What I was thinking was that  unless can be re-written as  if not and  ref $current_port eq "" as  not ref $current_port yielding
    next if not not ref $current_port;

Perhaps I should have written "implicit double negative". :)
