My proposal would be to make "scope" (with strong recursive

would give the compiler a lot of optimization potential (much
more than just for RC), and would at the same time most
probably be a lot less limiting. It would also be a nice
documentation trait to see where references are stored for
later use. And it could even be used to implement checked
safety for calling C/C++ functions with GC references.
Please see my newest scope proposal, which I just posted here:

It does almost what you suggest, but only for @safe functions, to
avoid breaking too many things. A change à la "@safe by default"
would then have the same effect.
