Comment (by akrzemi1):

 In order to stream out optional objects you have to include the IO header:

 {{{
 #include <boost/optional/optional_io.hpp>
 }}}

 I changed the implementation a bit, so that rather than a link-time error
 you get a compile time error about missing header. The change is now in
 develop branch.
