* Now `boost::optional` is specialized for reference parameters. This addresses a couple of issues:
* the `sizeof` of optional reference is that of a pointer,
* some bugs connected to copying optional references are gone,
* all run-time bugs caused by incorrect reference binding on some compilers are now turned into compile-time errors,
* you can swap optional references: it is like swapping pointers: shalow, underlying objects are not affected,
* optional references to abstract types work.
* Documented nested typedefs ([@https://svn.boost.org/trac/boost/ticket/5193 Trac #5193]).
