 Many Boost libraries have header variants with and without iostream
 support:

 {{{
 #include "boost/date_time/posix_time/posix_time.hpp" //include all types
 plus i/o
 }}}
 or
 {{{
 #include "boost/date_time/posix_time/posix_time_types.hpp" //no i/o just
 types
 }}}

 Likewise, there exists a macro BOOST_NO_IOSTREAM, which should prevent
 <iostream> from being included, see ticket #4060.

 Neither approaches are available in boost::rational<> but either could be
 put to good use.
