6618	boost::container::flat_map not transparently accepting move-only values	Charles David Tallman <DaveTallman@…>	Ion Gaztañaga	"I would have expected to be able to store move-only values in a boost::container::flat_map, and to have no code changes except in the header files, since it is supposed to be a drop-in replacement for std::map. However, I cannot create a key-value pair of a type it will accept, because of const errors. The attached program shows the problem.

Perhaps allowing a non-const std::pair reference to be passed to insert would help, or even a new make_pair helper function that returned a BOOST_RV_REF(value_type)?

The same thing happens with boost::container::map.
