Some things bear repeating.   And, let us always remember that TMTOWTDI, including the way that one chooses to create edifying blog-posts!   Even when one Monk does not do what you would have them to do exactly as you would have them do it, TMOWTDI, and if it did not do grievous harm, consider Silence.   The water Flows peacefully by, whether you choose to deposit Something into it or not.

The only axiom I might add to this interesting Meditation is:   “Look twice, code <never|once>.”   No matter what it is that you are doing, you are not the first one to have done it.   CPAN is a huge repository of what is called prior art, and as such it is sometimes a source of things that are to be used, and sometimes of things that are to be ... learned from, but otherwise avoided.   Both of these uses make CPAN a resource well to be studied, and to be looked-to first.   Perhaps a messy piece of coding might be entirely avoided.   Perhaps, a far better way of tackling a problem might be seen in someone else’s previous work.   Perhaps you discover in-advance something very smelly that otherwise would have soiled your boots.
