Motivation
I believe this is a design defect, and plan to ship it in 3.2.1 as a bug fix.
The semantics of
proxy_viewcan be reduced. Currently, one needs to useproxy<const F>to invoke any const conventions. With this change, users will have access to all the indirect conventions via aproxy_view<F>object as if it were aproxy<F>object.On the other hand,
basic_facade_builder::add_viewis removed due to incompatibility withsupport_view.Changes
observer_facade<F>to make it inherit all the indirect conventions fromF. Removed theconst Fspecializations.basic_facade_builder::add_view.details::proxy_view_dispatch. Changed the return type from a raw pointer to a new typeobserver_ptrthat is aware of the derecerenced types of the cv-ref qualified original pointer types.
