Comment:

 This issue was discussed in
 [http://lists.boost.org/Archives/boost/2013/01/200014.php mainling lists].
 If in short we have to choose between thre solutions:[[BR]]
 1) leave as is (slow move construction)[[BR]]
 2) allow empty state (fast, but breaks users code and variant
 guarantees)[[BR]]
 3) after move, do lazy default construction of value on request (fast, but
 adds default construction requirement for type and functions get() and
 get_ptr() may throw)[[BR]]

 There were more votes for solution 1.
