This would be educational; I think you should call it The Duffer's Guide to Perl Golf.

Naturally, there would be companion volumes:

• The Duffer's Guide to Perl Obfuscation

• The Duffer's Guide to Perl Idioms¹

• The Duffer's Guide to Perl Modules

• The Duffer's Guide to Useful Perl Regular Expressions....(wait, you're already writing that).

...and so on...

--f (being only slightly facetious)

¹ - Yes, I'm well aware of the, um, er...Pearl book, but this would be geared for those of us still learning which clubs to swing and when.
