Re^2: 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. "I'm fairly sure if they took porn off the Internet, there'd only be one website left, and it'd be called 'Bring Back the Porn!'" -- Dr. Cox, Scrubs	[reply]

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". :)	[reply] [d/l] [select]
