[Vane, Edwin]

Would you log an enhancement in bugzilla too?

Subject: Suggestion for C++ migration tool: tr1 removal

TR1 was a very successful add-on to C++03.
However, most (if not all) of the bits of TR1 are now part of the C++11 standard.

Some c++11 standard library implementations include the TR1 features (libstdc++, Dinkumware), while others (libc++) do not.

I think it would be great if the c++11 migration tool "migrated" away from using tr1 features in favor of using the ones in std.

For example:

    #include <tr1/unordered_map>
    int main()
    {
        std::tr1::unordered_map <int, int> ma;
        std::cout << ma.size () << std::endl;
        return 0;   
    }

should be rewritten to:

    #include <unordered_map>
    int main()
    {
        std::unordered_map <int, int> ma;
        std::cout << ma.size () << std::endl;
        return 0;   
    }


and so on.

Comments?
