Subject: [PATCH] Handle changes to boost::optional in newly released boost
 1.56: To improve compatibility with the proposed std::optional a number of
 changes were made, one of which is the removal of the implicit conversion to
 bool.  As a result, returning boost::optional as a bool value now fails. 
 Explicit conversion to bool used for clarity.
