Re: [boost] deprecated: MPL, foreach, typeof, ratio, chrono, assign, more?

What would be the meaning of such markup?

When we mark some parts of library API as deprecated we intend to eventually remove it. Are you proposing to remove these libraries after the deprecation period?

What would you recommend to do to users of these libraries, both within and outside Boost? Note that in some cases it isn't possible to port from these libraries without also breaking user-visible API in downstream libraries. So removing those libraries will have implications beyond their direct users.

The idea here is to discourage use of these libraries in new code. Maybe we could just put them into their own dedicated section at the end of the list.
