Comment (by pbristow):

 Your fix is fine, and may be best for some applications, but we feel it
 reads verbosely.

 So we have decided to recommend a different way in our examples.

 We recommend *NOT* "using namespace anything;" std, boost::math ...

 but to qualify each distribution used after the

 #include <boost/math/my_distribution>

 like

 "using boost::math::my_distribution;"

 (and "using std::cout; ..." if you wish - worthwhile clutter reduction if
 there are lots of calls to cout, as is common in cpp source files, but
 calls are less common in .hpp include files.)

 This can be done globally or locally in source .cpp files, but should be
 only locally in .hpp include files.

 All our examples will now follow this recommendation.
