+// The buffet::Any class can hold any C++ type, but both the setter and

+// data pointers. Any will not copy a contents of the array.
+//    const int data[] = [1,2,3];
+//    Any v(data);  // stores const int*, effectively "Any v(&data[0]);"
+
+// buffet::Any is a value type. Which means, the data is copied into it
+// and Any owns it. The owned object (stored by value) will be destroyed
+// when Any is cleared or reassigned. The contained value type must be
+// copy-constructible. You can also store pointers and references to objects.
+// Storing pointers is trivial. In order to store a reference, you can
+// use helper functions std::ref() and std::cref() to create non-const and
+// const references respectively. In such a case, the type of contained data
+// will be std::reference_wrapper<T>. See 'References' unit tests in
