Let's carefully consider this one:

A "left overs" or "hodge podge" of snippets doesn't belong in a module, but should be part of the programmer's knowledge base.

The snippets that are common knowledge to a significant portion of the community ought to be taken out of our personal, back-of-the-brain closets, dusted off, and given proper names. Let us place them firmly in the common, community-wide knowledge base.

Why should every programmer in the community have their own pet versions of common but "noncollectable" functions? If there is value in giving something a name, give it a name. If there is value in collecting something, collect it.

Who cares how big the thing is or whether there's already enough stuff like it to form a ready-made home for it? If the cost of giving it a name and collecting it and then using it to solve problems is less than the cost of solving the problems otherwise, then it has earned its name and its place. What other consideration is there?

Cheers,
