Looking back at HTML::Template, I count a total of 31 params passed to its constructor. Granted, some of them would never be used together (such as arrayref and filename), but it will accept that many. Despite this fact, the module doesn't strike me as having a bad design. Most of those params would need to be passed to a subclass anyway, and the few params left over (perhaps some of the caching options, strict, or die_on_bad_params) just don't make it worth the trouble of inheritance (IMHO).

Further, inheritance is a major kludge in Perl5 (kludgier than the rest of its object system), and should generally be avoided if possible.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
