A stack of stacks would be fairly trivial to implement in terms of code but is such a thing ever useful or used in practice? Is there a common name for such a monstrosity?
@Shog9 he doesn't have to type, he wills the input and the registers spontaneously change state

@Atif and the answer I think to that question is that you could use a stack of stacks to do deeply nested recursive functions where each item in the first stack is a function call which then sets up a new stack at that point.
