Does anyone understand how to use "shared" types with concurrency send/receive functions?

I tried it too some time ago. Then I read Alexandrescu book and 
realized that the authors of the language do not want anyone to 
do this. Long story short, just plan your application so that 
each complex object is monitored by only one thread/task, and 
pass not objects, but messages (immutable structs) about what to 
do with them.
