boost make_shared takes in a const reference. Any way to get around this?

http://www.boost.org/doc/libs/1_39_0/libs/smart_ptr/make_shared.html says: “If you need to pass a non-const reference to a constructor of T, you may do so by wrapping the parameter in a call to boost::ref.” Other text on that page seems to support Rüdiger Hanke’s answer.
