            Bug ID: 41882
           Summary: Non-type template params with braced-init-list
                    initializers are not supported
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++

template <int = {}> void f(); // expected expression

One of the things nobody uses, it doesn't even have a TODO somewhere or a
intentionally broken test AFAICT. 

We should probably start supporting this, with C++2a's class type non-type
template parameters potentially making this kind of construct more popular. :)
