I don't get to excited about using fewer operators. I let map() work on the data and grep() pick out which elements it wants. 

my @lines = grep length(), map { s/#.*//; s/^\s+|\s+$//g; $_ } <$in>;

Update japhy's right that that s/// with the alternation is slow. It's even in the perlfaq, and I know that because I updated that answer recently. That's what I get for golfing the line to not break with the code formatter thinger. :)
