[Boost-users] [type traits] Extension to operator detection -> choose your preferred naming

It is time to include the type trait extension to the official boost trunk. These traits can detect if you can use a given operator with given arguments. For example: has_plus<double, int>::value is true because the following program compiles without error: double lhs; int rhs; lhs+rhs; We have come to three proposed lists of names (A, B and C): https://svn.boost.org/trac/boost/wiki/GuideLines/Naming/OperatorTraitNames I have included the corresponding names of standard keywords, standard function objects from <functional>, boost Proto and boost Operators. Please give your preference between A, B and C before Sept. 5th. Regards, Frédéric
