There are many reasons why a programmer should "touch a working system." (Of course he should keep a backup. He may need it.) In this case, the OP is trying to improve his perl skills.

A "working system" may pass its functional tests, but fail any test for maintainability. These should be treated the same as any other failure. The sooner they are fixed, the lower we can expect the total life-cycle cost to be.
