while (chomp(my $line = <DATA>)) {

This won't work if the final line doesn't end on a newline, as chomp returns the number of newlines it removed. Better to use the traditional while (<DATA>) { chomp; ... or while (my $line = <DATA>) { chomp($line); ... Update: Plus, even with a trailing newline, the code generates a warning, since after the final line, the loop condition is executed one more time, and <DATA> will return undef and chomp(my $line = undef) causes a warning.
