           Summary: [C++0x] cannot use T{t}... as pack expansion
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: r...@gcc.gnu.org
                CC: ja...@gcc.gnu.org


template<typename... T>
    void f(T...)
    { }

template<typename... Args>
    static void
    g(Args&&... args)
    {
        f( static_cast<Args>(args)... );

        f( (Args)args... );

        f( Args(args)... );

        f( Args{args}... );   // ERROR
    }

int main()
{
    g(1, '2', 3.0);
}

The line marked ERROR fails, it should be equivalent to the previous statement
