I can't think of a reason to ever use TR1 (and whichever version of result_of) in C++11. Even less so in C++14, which will have deduced return types unless the N3638 formal motion failed, and I very much hope it did not.
Agreed, and we recommend in the boost::result_of documentation that C++11 users use std::result_of rather than boost::result_of. However, one reason to use TR1 in C++11 is to make code more portable to/from C++03, which is an important use-case for boost::result_of right now. This is one reason why we require explicit user action to change the default (TR1) behavior on sub-standard C++11 compilers: to promote portability and to minimize the effort needed to compile existing C++03 code. - Daniel
