Are there any plans (or is it already happening) to make
D-compilers automatically use stack allocations when possible

int foo()

auto x = [1, 2]; // should be allocated on the stack

}
where allocations are "small enough" and cannot escape the
current scope?
And how does/should/will this interact with `@nogc`?
LDC does something like that IIRC.
It does.
https://github.com/ldc-developers/ldc/blob/master/gen/passes/GarbageCollect2Stack.cpp
It is enabled by default at -O2 or higher (but not -Os or -Oz).
