The obvious one: don't use a module.
My initial reaction to this snide remark was to dismiss it as yet another exercise in sarcasm. However, looking back at my post, I suppose I didn't make it clear that the purpose of the seminar is to teach the inside-out technique, and, particularly, its pros and cons. I also want to give an overview of the "gazillion" modules that are springing up, so people understand what each one brings or doesn't bring.
As to the gazillion modules, what's the alternative? Every programmer going out and making their own gazillion mistakes writing everything by hand? At least CPAN modules, flawed as they might be, have the potential to benefit from some degree of peer review, experience and bug reports. (c.f. the growing Class-Std bug list)
What I find slightly amazing is that none of the tech reviewers for PBP picked up on any of the potential design issues before Damian went out and declared inside-out objects as
the new best practice.
