[boost] [multi_array] swap

Hi, The swap support for multi_array was under discussion from the very beginning. A multi_array is quite a heavy object so having light-weight and no-throw swap would be really great. In 2009 a patch was proposed (https://svn.boost.org/trac/boost/ticket/1045) and Ronald Garcia generally liked it, but planned to do some extra work before adding swap to multi_array (see the comments for the ticket above). What is the current status? Thanks, Maxim
