I'll have to agree with Abigail, I don't think theres a need for a whole section on it, and programming style is a matter of taste. There are probably many reasons to use both sides of the examples you mention.
(And shouting 'use strict' all the time gets on my nerves too, I've yet to see the benefit apart from making Perl more VB like.. ;)

There's no reason not to write meditations/tutorials on programming style though, as long as the pros and cons are explained.
