This doesn't address any of the 3 concerns.
1. RC efficiency is architecture dependent. E.g. TSX is coming
even if there is a bug in lower end CPUs. Suggest making
performance oriented prototypes on different architectures before
concluding.
2. As long as you have a RC pointer to an obj on the stack you
can switch to regular references. No magic involved for the easy
case, just semantic analysis.
3. True, but you can keep the refcount at a negative offset for
new-based allocations. Besides it only affects those who do @nogc
and they should know what they are doing.
