so how about while (my $line = <FILE>) instead of using $_?
Evil! An empty line, or a line with only a "0" in it.
Not quite. Lines are not completely empty. A blank line would have
"\n". A line with just zero would have "0\n". Only after a chomp would
the test fail.
WARNING: Evil code, do not use:
while( chomp( my $line = <FILE> )){
That is not "evil" but it won't work correctly if $/ is not found at the
end of $line or $/ does not contain a string.
