Everyone else gave you a bad transliteration of your loop. The proper rephrasing of that is 
while( my $line = <> ) {
    last unless $line =~ /\S/;

    # ...
}

That is, your loop does not merely skip lines which do not contain non-blanks, it actually terminates as soon as it encounters one.

Makeshifts last the longest.
