5810,BOOST_STATIC_ASSERT requires unnecessary parentheses,tsoae@…,John Maddock,"In Boost 1.47.0 the BOOST_STATIC_ASSERT macro is defined as having one parameter. When the argument contains comma-separated template arguments, we (sometimes) have to use additional parentheses:

    BOOST_STATIC_ASSERT(is_base_of<B, D>::value); /* error: two arguments passed */

    BOOST_STATIC_ASSERT((is_base_of<B, D>::value)); /* OK */

Today many C++ compilers support variadic macros, so for such compilers BOOST_STATIC_ASSERT might be defined like this:

    #ifndef BOOST_NO_STATIC_ASSERT

    #   define BOOST_STATIC_ASSERT(...)               \
            static_assert((__VA_ARGS__), #__VA_ARGS__)
    #else
        ....

and BOOST_STATIC_ASSERT(is_base_of<B, D>::value) might be correct. Are there any problems with such definition?",Bugs,closed,To Be Determined,static_assert,Boost 1.47.0,Cosmetic,fixed,,
