I don't follow this.. stacks don't allow dynamic allocation per
stack-frame, while dynamic regions do.

To me this makes them seem like entirely different beasts. With
call-stacks, allocation and deallocation is mutually bound to the
stack-frame-return. While with dynamic-mutable-regions, we quickly can
witness situations where we would like to reclaim independently of any
statically analyzable motion between stack-frames or blocks.

By my view, stacks could be said to be similar to only
static-sized-regions, or immutable-dynamic-regions.

Which one of us confused?
