This is a much more powerful way to handle things, as this take
advantage of inlining.
More powerful than what?
Rather than thinking in terms of alloc/free it might be helpful
to think about it more generally as resources, use, reuse and
side-effects. On the stack you get to reuse memory when the
variable is not longer live, meaning you junk writes if the
results cannot be read and reuse the memory "prematurely".

If you are saying that turning GC allocations automatically into
stack allocations is a good direction for D2, then I agree.
