Yes, you should define BOOST_RESULT_OF_USE_DECLTYPE. As a general rule of thumb, the only time you should not define BOOST_RESULT_OF_USE_DECLTYPE is if you are working with C++03 code. In fact, on more compliant C++11 compilers (e.g. clang 3.1, gcc 4.8.1, msvc 12), decltype will be enabled by default.
