Yah, could be part of the metadata. Then after inspecting that
bit, shared can be casted away. I consider that an optimization
that doesn't add or remove generality. -- Andrei
I was actually suggesting encoding the shared-ness into the
memory address itself. (No tricks - just allocate shared data in
a separate memory range. This may only be feasible on 64-bit
though, with its over-abundance of address space.)
This way, you can determine whether the (meta-)data is shared
without accessing it at all, just by asking the allocator about
the address.
