Your class will have strong typed properties so your values will still be type checked. Eric: A great solution! I've seen plenty of this going on with anonymous objects passed as parameters (AS3 Tweener class for example) but never as a concrete parameters class. I think i'll finally update some of my more unwieldy methods, thanks :) William: the parameters object is an instance of an actual parameters class you created specifically for the method your creating it for.

Suppose z in the params object is meant to be a string and not a number as passed, how do we guard against that? But how do we account for type checking at compile time.
