Shared-between-threads and shared-between-scopes are orthogonal properties; using "our" or "my" controls access by lexical scope; something else is needed to control access by thread, and ":shared" is as good as anything. The only exception to this orthogonality is that anything within a closure is not shared between threads -- but of course, that is only sensible because it is not even shared between multiple closures *within* a thread. -Martin
