13161	Optional vector assignment regression	popizdeh@…	Fernando Cacciola	"{{{
boost::optional<std::vector<int>> v;
v = { 1, 3 };
}}}

Assignment doesn't compile anymore. It worked in 1.62 and reports an error in 1.63. I think it has to do with the addition of BOOST_NO_CXX11_UNIFIED_INITIALIZATION_SYNTAX but I could be wrong.
