A better way to avoid public member invisibility and source code bloat/repetition with inherited class templates?

by

Use macros to simplify Solution #3 somewhat. Boost is not strictly necessary, but makes life easier.

#include <boost/preprocessor.hpp>

#define USING_ONE(r, base, member)              \
    using base::member;

#define USING_ALL(base, ...)                    \
    BOOST_PP_SEQ_FOR_EACH(                      \
        USING_ONE, base,                        \
        BOOST_PP_VARIADIC_TO_SEQ(__VA_ARGS__)   \
    )

// Near CBase<BYTES>
#define USING_CBASE(param) USING_ALL(CBase<param>, Arr, Fn1, Fn2, Fn3, Fn4, Fn5)

// In CDerived<BYTES>, in a `public:` section
USING_CBASE(BYTES);
