[boost] [TypeTraits] is it possible to add something to boost.type_traits?

Dear boost implementers,
TypeTraits is very useful, thanks you.
However, recently, I needed something to know if a type is comparable (with operator<) and that was not in the library.
Fortunately, somebody forwarded me an earlier post on the users list where I could find what I wanted. The implementation was inspired from boost/detail/is_incrementable.hpp
I have written is_less_comparable, is_less_equal_comparable, is_greater_comparable... inspired from the same source and I wonder if it could be possible to add it to the library as I think it could be
helpful for others. I give the source code below (if it is useful) but I am not able to make it fully general as it is in boost/type_traits. In particular, I do not understand all the macros that are
used.

Regards,

F. Bron
