Yes indeed, for a plain proxy. Unfortunately for a lazy proxy this is not acceptable as it would "create" (or "access") the target. The point is to delay that till it's actually needed, not when the proxy is created. Thanks, -- Ionel Cristian Mărieș, http://blog.ionelmc.ro

Yes indeed, for a plain proxy. Unfortunately for a *lazy* proxy this is
not acceptable as it would "create" (or "access") the target. The point is
to delay that till it's actually needed, not when the proxy is created.
