No, I don't have the fall-through capability, natively. One would have to have the functions themselves call each other to gain fall-through. (If 'A' would fall through to 'B', then A() does a return B(@_); at the end.) This is somewhat counter-intuitive and very tightly coupled, but it does have benefits.

The primary benefit I see, apart from the dynamic nature of it, is that I can pass args to my switch clauses. In addition, I've separated out my switch clauses from one another, which means that they can be arbitrarily long and not go over-long within the same function.
