I hate these explicit casts. It is impossible sharing anything 
between threads without these ugly casts from/to shared. Seems 
like something wrong in program design when I'm forced to use 
explicit casts. But I don't understand what is it exactly.

You don't need to mark Tids as shared.

For example. I need create mutable object in one thread and 
send to another. I don't need to share this object, just 
create, send and forget. But I have no idea how make this 
without using shared attribute and casting to/from it.

If you originally create it as shared, you don't need to do the 
casting.
