--- Comment #7 from petschy at gmail dot com ---
After this fix, the following code doesn't compile:

template<typename T>
struct Ptr
{
        Ptr& operator=(T* p_)
        {
                return operator=<T>(p_);
        }

        template<typename U>
        Ptr& operator=(U* p_)
        {
                ptr = p_;
                return *this;
        }

        T* ptr = nullptr;
};

$ g++-8.2.1 -Wall -std=c++11 -c 20181204-templated_opeq.cpp
20181204-templated_opeq.cpp: In member function ‘Foo<T>&
Foo<T>::operator=(T*)’:
20181204-templated_opeq.cpp:6:21: error: expected primary-expression before ‘>’
token
   return operator=<T>(p_);
                     ^

On the gcc-8-branch, the commit before the fix (a9a931e4) is OK. 7.3.1
(4c925b84) is OK. Tested on Debian Stretch, AMD64.

Is the above code invalid?
