Re: [Boost-users] Testing that a particular operator is not alllowed

Frederic Bron wrote an extensive list of traits meta-function for that. It was in the sandbox but I don't remember if it's in trunk atm.

You can find here what I did: http://article.gmane.org/gmane.comp.lib.boost.devel/194625 If you browse in the sandbox, you will see in boost/type_traits some files is_..._comparable.hpp. I never finished the action to have it included in boost because at some point some said this was already implemented in a unmaintained library of the sandbox (https://svn.boost.org/trac/boost/wiki/LibrariesUnderConstruction#Boost.Conce...). I still have the project to propose something but lack of time. Frédéric
