Sorry, I didn't know that. I have thought that the removal of the scope
attribute was only for class instances.

Even if the scope attribute can't be used on dynamic arrays, the last point I
have expressed applies still: if the compiler is able to perform escape
analysis (LLVM has some of such capability) and it can statically verify a
dynamic array never escapes, then if a runtime test shows such dynamic arrays
is small it can be allocated on the stack.
