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.
We are the carpenters and bricklayers of the Information Age.
Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
