Per the current spec, this would not be a valid use of scope, as scope is 
specifically a parameter storage class and can only be used on function 
parameters (just like in, out, ref, and lazy). scope seems to be specifically 
intended for guaranteeing that an argument passed to a function does not 
escape that function.
