Even if the library doesn't provides an approach that works to define all the concepts, it has a lot of useful things. I also suggested to Terje at least to add the mpl and type traits extensions of the library.
Agreed - in fact I don't see why we can't just add the new traits direct to the type_traits library?
Certainly if someone would like to package these up as direct additions to type_traits (so I don't have to do much!) then I'd certainly look favorably on adding them.
I will work on doing so if it is OK with the original authors of the library. I can do this for the type_traits_ext in the CTL. I would also like to see the operator detection in the CTL added to Boost, even with the known limitations for operators which must be member functions, but I do not know if you feel this would also be an addition to the type traits library ? I know that Frederick Bron has added some traits to the type_traits in the sandbox which are a subset of all the operator traits in the CTL but he appears to have stopped with what he was doing because he found out the CTL already existed.
