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
::value is true because the following program compiles without error: double lhs; int rhs; lhs+rhs;
This checks for the ability to add lvalues. Is there a way to check for rvalues? Just curious.
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.
