Comment (by anonymous):

 I also encountered this problem recently. It prevents me from using
 boost::any_range as an object interface abstraction, since i don't want
 the values copied (i want to expose iterators to Base, and supply a
 container of Derived objects in the implementation).

 I do not see any good reason to require copying when all any_range is is
 an abstract view into the source range. That elements aren't going to be
 copied should be made into a guarantee.

 This is a 2 year old bug, is it possible that it can be fixed soon?
