constructor_as_function and std::initializer_list

[theodelrieu]

Hi, I think there is a problem with the implementation of constructor_as_function.

return T{args...};

IIRC, make_unique uses parenthesis instead of curly braces, I believe we should do the same.

Here is the current behavior:

struct Test {
  Test(int, int){} // 1
  Test(std::initializer_list<int>){} // 2
};

fplus::constructor_as_function<Test>(4, 2); // will call constructor 2

Good catch!
