<pre>When compiling the following code with `clang++ -std=c++17 Test.cpp`
template <typename T>
struct Test {
template <typename U>
friend bool operator==(Test, U) = delete;
};
Test<int> test;
I get the following unexpected error:
> clang++ -std=c++17 Test.cpp
Test.cpp:4:15: error: redefinition of 'operator=='
friend bool operator==(Test, U) = delete;
^
Test.cpp:6:11: note: in instantiation of template class 'Test<int>' requested
here
Test<int> test;
^
Test.cpp:4:15: note: previous definition is here
friend bool operator==(Test, U) = delete;
^
1 error generated.
GCC 7.2 produces no error.</pre>
