Taking the address of a ref variable has not been allowed in

Which is understandable given things as they are, but which could
probably be relaxed given good scope/lifetime analysis by the
compiler...?
The above code is unsafe only if the lifetime of `data`
outlives the lifetime of
`input`. Surely the new scope rules should be able to
distinguish the cases?
If that's already envisioned, how would that work?
That depends on how the instance of MyWrapperStruct is
allocated. How did you intend to allocate it?
As a normal stack variable. Is that problematic? And if not, what
would be problematic cases?
