In a pure object oriented approach, if you have a lot of varying parameters is a sign that you might need to reify the parameters as a first class object, i.e. "SomethingParameters" class or similar, then instead of passing 1...n objects that will work as parameters you only pass one object, aSomethingParameters. Of course it adds more friction to something that maybe the language could provide, but in Smalltalk everything is explicit. I would be interested in the use cases and how to deal with "undefined" arguments, will they be nil or other kind of undefined object? Regards! Esteban A. Maringolo
