Looks like I broke it in https://svn.boost.org/trac/boost/ticket/6999 .
Should I create a new ticket:-)
Fixed in trunk.
Great!

BTW, draft tells nothing about any_cast(instance_of_any).
Current Boost version will return rvalue if `instance_of_any` is not
const and fail to compile other way.
Interesting!

To movable_test.cpp, I added:

    std::cout << "move assign from any contents by rvalue reference"
<< std::endl;
    m = any_cast(x1);

Worked for the current Boost trunk with both GCC and VC++, but VC++
2012 produced a warning:

c:\boost\trunk\boost\any.hpp(272): warning C4172: returning address of
local variable or temporary
          c:\dot16\dot16\test\movable_test.cpp(61) : see reference to

boost::any_cast(boost::any &)' being compiled

              ValueType=movable &&
          ]
