I just finished a pull request <https://github.com/boostorg/mpl/pull/14> with
a fix for Ticket #11001 <https://svn.boost.org/trac/boost/ticket/11001>,
which, by the way, I reported myself, so I'm quite confident it's fixed.
Could one of the maintainers kindly review it?

Oh and it is worth it to mention that I also included a new test case to
ensure the fix is working.

Kind regards,
