Since it's `scope`, where would it be copied to? This is assuming dip1000, of

The rethrow case must be allowed:
throw ex;
Then either:
1. Elide the destructor call in that situation
That's Andrei's "move semantics" idea, and it involves major code effort in the
compiler.
There's the "chain" case, too.
2. Make the developer write `throw ex.dup`
The point is to not require them to rewrite their code.
I'd prefer #2, since it would make a lot more sense for `scope`. `throw` escapes
the ex IMHO.
