in reply to module advice

Generally speaking, when methods require too many arguments, thats a symptom of a God Object. Refactoring a God Object is going a few steps past the "Currying" concept. In a nutshell, objifying more things gives you grainularity on state. Using one large object prevents structure form arising out of the chaos of your program (well, any program, I'm just being dramatic). Good user interfaces often take the form of creating one object, passing it options, then passing that object as an option to the constructor of another object. Each object contains configuration associated with what it represents in the world, and part of the configuration of other objects is the configuration already performed on existing objects. Pod::Tree and its related modules are an example of this. Feel free to email me at scott@slowass.net or markup the wiki pages at perldesignpatterns.com - I don't read comments, only headlines, and only sometimes. And whoever is doing that thing that gives me experience, stop it! I'm trying to lay low. -scott
