Once the aggregate struct data is decl-ed `shared` as a whole, it 
needs to be transitive to play safe.

The compiler (technology) is not that advanced enough to either 
prove that for a particular sub-component of a shared struct data 
is fine without protection, or the programmer's intention.

If the programmer is really sure about his/her design, just 
cast() the `shared` away.
