Is this a use beyond simply saving keystrokes, or did I misunderestimate what you wrote?

    No, we're not just saving keystrokes here. We're saving repeated calls to the lvalue method. And, even though method calls in Perl 6 will be faster, not doing any calls in the loop is still a real saving if the loop iterates many times.

      So at what point does the lvalue method get called, once $thresh goes out of scope, or once the object is accessed, or at some other time?

        If I understand correctly, you can think of it as roughly akin to a lexical glob assignment. So the lvaluable (lvalued?) method is called on each assignment to $thresh. The moon stays the same, but there are several fingers, each with a different name.
