Re: [boost] [result_of] Regression: compilation errors on C++03 compilers when defining BOOST_RESULT_OF_USE_DECLTYPE

If we define BOOST_RESULT_OF_USE_DECLTYPE, boost::result_of tries to use decltype-based implementation even on C++03 compilers. This causes compilation errors and it is a regression on C++03 compilers.

How do you expect boost::result_of behave in this case? I will be surprised if when requesting it to use decltype, boost::result_of used instead any workaround. The best think the library could do is to report an explicit error and/or provide a BOOST_RESULT_OF_USE_DECLTYPE_IF_AVAILABLE which could behave as you are requesting. Just my 2cts, Vicente
