>Description:
In the attached program the parameter 'int (T)' is parsed
as a parameter of type int called T with redundent parentheses. This is incorrect. It should be parsed as an unnamed parameter of type 'function taking T and returning int'. [8.2]/7 gives this ambiguity and resolution. An example
  class C {};
  void f(int (C)); //void f (int (*)(C))
is given
