I'm curious as to why using scope to allocate classes on the stack was marked for future deprecation.
It was never implemented correctly (it is supposed prove it never leaves the scope, and is thus safe to be on the stack), so rather than keep a half baked feature in the language, the gang wanted to move it to the library where at least the usage wouldn't look as normal given the memory safety problems.
