Re: [Boost-users] Template metaprogramming technique for operator overloading

Edward Diener a écrit :

I could not find this in type_traits, or any other Boost TMP library, but I am wondering if there is any TMP technique which can determine if a user-defined type supports a particular operator overload for that type ?

I don't think you can do it without SFINAE extended to expressions. This is available in C++0x and certain C++03 compilers, such as GCC starting with version 4.4 (or is it 4.5?)
