in thread Hash of arrays of hashes

next unless ref $current_port eq ""; # skip if $current port is NOT a +scalar.

Wouldn't this be better if more directly stated as
    next if ref $current_port;  # skip if $current port IS a reference
thus avoiding the double negative?

    Agreed that your code is shorter/better. Disagree that mine has a double-negative.

      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". :)

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

        unless is pronounced "unless" not "if not"
