Makeshifts last the longest.

In some ways Principle #5 goes against Perl's grain, or at least it seems that way to me. Taking advantage of all of Perl's logical (implicit) defaults is what makes the code I write in Perl so small.

These are great suggestions though, and probably even #5 is well worth applying even in Perl.

This is probably one of those "all things in moderation" areas. In general I try not to specify defaults because they distract from the truely interesting unique components. So I'd probably look at a default-ful chunk of code and have to pick through those to find the non-defaults. It's more time, more work and generally harder to work with default-ful code. Or that's true (for some value of true) for me anyway.
