 I'd like to have a generalization of BOOST_PP_ENUM_BINARY_PARAMS() to 3
 parts. This would be useful to generate the parameters of a function like
 {{{
 template <typename F1, typename T1, ...>
 int CompareFields(F1 T1::*f1, ..., FN TN::*fN);
 }}}
 which can't (unless I'm missing something) be easily generated currently.
 And looking at `boost/preprocessor/repetition/enum_binary_params.hpp`
 implementing this manually doesn't look very simple so it would be nice if
 the library could provide it.

 I could (try to) make a patch adding this myself if it has any chance of
 being accepted, please let me know if it would be.
