           Summary: Parenthesized id-expression in function parameter pack
                    not allowed
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org

Clang doesn't like this:

    template<typename ...T>
    void f(T (...t));

which is equivalent to 

    template<typename ...T>
    void f(T ...t);

It says

main1.cpp:2:14: error: expected ')'
void f(T (...t)) { } 
             ^
main1.cpp:2:10: note: to match this '('                                         
void f(T (...t)) { } 
         ^
main1.cpp:2:6: error: declaration type contains unexpanded parameter pack 'T'   
void f(T (...t)) { } 
     ^ ~
2 errors generated.
