Moving a reinterpret_cast from user code, where it's visible, to the queue 
implementation, where it's hidden, decreases type safety instead of 
increasing it. A typed interface is only meaningful if the queue enforces 
type safety, perhaps by encoding the type (and ideally the compiler version) 
somehow.
