I have had a solution to this since before @live that I was screaming 
about in the guise of DIP1000's last big hole.

Xor mutable references with borrows.

Protects against assigns, function parameter passing, doesn't need any 
extra syntax...

I am highly annoyed by this. THIS WAS SOLVABLE WITH SOMETHING I HAVE 
BEEN SCREAMING ABOUT FOR ALMOST THIS EXACT THING.

If this is literally the *only* thing blocking RC, I can do the DIP for it.
