It would really be nice to have type_traits for all the possible user-defined operators. The operators which can be user-defined as specified in the C++ standard. These are given in 13.5 1, as:
new delete new[] delete[] + - * / % ˆ & | ˜ ! = < > += -= *= /= %= ˆ= &= |= << >> >>= <<= == != <= >= && || ++ -- , ->* -> () []
I will stick to binary operators. Thus I leave the others to somebody else because I have been working on it for quite a long time now and would really like to see it in boost soon. Each time a feature is added, it takes very long to make everybody agree on the details which is very good because the resulting code is very high quality then. Also I have not enough time at the moment (and probably up to March 2010) as I am working on a large time consuming musical score project. Therefore if you want to start some work on unary operators, please feel free to do it.
OK, thanks ! I will look at is_incrementable in boost::detail to see if I can understand it. The technique used there should theoretically scale to the other unary operators.
