Today, I am not seeking... but rather sharing a profound pearl of wisdom that I found while diving beneath my comfort zone of Perl. This applies to "system" as well as "software development":
These three tactics are presented in increasing order of “cleverness.” Such cleverness should be used only when necessary, since it requires a corresponding application of cleverness on the part of the maintenance programmer eight weeks later, and such cleverness may not be available.

It is always better to have seen your target for yourself, rather than depend upon someone else's description.
