   Bonjour

      It looks as though the Boost.Test doc has a slight sync issue.

      The BOOST_CHECK_PREDICATE macro is described (in file 
boost/libs/test/doc/components/test_tools/reference/index.html) as 
having to be used thus:

   8><   -------------------------------------------   ><8   

int test.cpp( int, char* [] ) {
    int i = 17;

    BOOST_CHECK_PREDICATE( std::not_equal_to<int>(), 2, (i,17) );
//                                                  ^^^^^^^^^^

    return 0;
}

   8><   -------------------------------------------   ><8   

whereas Boost.Test's test uses (in file 
boost/libs/test/test/test_tools_test.cpp) the following form:

   8><   -------------------------------------------   ><8   

    using std::not_equal_to;

    CHECK_TOOL_USAGE(
        BOOST_CHECK_PREDICATE( not_equal_to<int>(), (i)(17) ),
//                                                 ^^^^^^^^^
        output.is_equal( CHECK_PATTERN( "error in " TEST_CASE_NAME ": 
test not_equal_to<int>()( i, 17 ) failed for ( 17, 17 )\n", 2 ) )

   8><   -------------------------------------------   ><8   

      Of course the later compiles while the former does not.

   Merci
