Shared today is a half-baked implementation of a half-thought 
idea. Manu wrote[0] almost two years ago what it should be: you 
can't read or write from a shared object, and only shared methods 
may be called on it. This was made into a DIP[1], and is 
half-way(?) implemented in the compiler as 
-preview=nosharedaccess. The semantics are effective and easy to 
understand.
