We get on the trunk:
t.cc: In function ‘int main()’:
t.cc:21:33: error: no matching function for call to ‘Op<int>::Exec(int,
<unresolved overloaded function type>)’
t.cc:21:33: note: candidate is:
t.cc:13:14: note: static bool Op<T>::Exec(T, Op<T>::op_func) [with T = int;
Op<T>::op_func = bool (*)(int)]
t.cc:13:14: note:   no known conversion for argument 2 from ‘<unresolved
overloaded function type>’ to ‘Op<int>::op_func {aka bool (*)(int)}’
t.cc: In instantiation of ‘static bool Op<T>::Exec(T, Op<T>::op_func) [with T =
int; Op<T>::op_func = bool (*)(int)]’:
t.cc:21:11:   required from here
