7250,rational.hpp imports header iostream even if stream operators are not needed,Levente Hunyadi <levente@…>,Jonathan Turkanis,"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.",Feature Requests,new,To Be Determined,rational,Boost 1.51.0,Problem,,,
