How does a delegate with a stackpointer work? e.g. in this
example:

Does the second call to foo not overwrite the stack of the
first call and thereby the data pointed to by bar1? How is that
data preserved?
Why should a call to foo overwrite something? Aren't these two
foos equivalent from this point of view?

DelegateT foo1() {

auto foo2()
