            Bug ID: 16118
           Summary: can't expand a parameter pack into a list of function
                    types
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org
          Reporter: eric at boostpro.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

See the following:

  template<typename ...Ts>
  struct list
  {};

  template<typename ...Ts>
  struct S
  {
      using type1 = void(int...(Ts)); // (1) works
      using type2 = list<int...(Ts)>; // (2) fails
  };

The line marked (1) works, but the (2) does not. The syntax is a bit weird, but
I think (2) should compile, and the result should be a list of function types.
