I agree with Andrei here. Alternatively perhaps the runtime can move the
data to a global pool if it's casted to shared.
I think a reasonable solution (in case we're unable to solve this
reasonably within the type system) is to offer a library solution that
does the shared allocation, mutation, and casting internally.
Again: USER CODE SHOULD HAVE NO BUSINESS CASTING CASUALLY TO GET WORK DONE.
