We are all familiar with the standard advice. Use strict.pm. It catches typos.

But as you're well aware there's more to it than catching typos... at least for those whose Perl_fu is less than "expert."

And then there's the addendum, which you didn't quote, of which this is one variant:

"...unless you know what you're doing and why you're doing it."

Now, I see that you didn't ignore this, but given the high regard in which you're held, I fear some less-knowledgeable coders (especially those who merely scan the first few lines) might wind up telling themselves "but tilly said I shouldn't use strict. Of course, you did no such thing, which is what makes your meditation worth CAREFUL and thoughtful reading, even by those to whom I have imputed "lesser fu" or impatience (and, BTW, to /me).
