+	/// .Array flavor
+
+	/// If elements are not `Moveable` and therefore cannot be stored in `Vector` flavor, they
+	/// can still be stored in `Array` flavor. Another reason for using Array is the need for
+	/// referencing elements - Array flavor never invalidates references or pointers to them.
+	/// Finally, if sizeof(T) is large (say more than 100-200 bytes), using Array might be better
+	/// from performance perspective.
+
+	/// Example of elements that cannot be stored in Vector flavor are standard library objects like
+	/// `std::string` (because obviously, standard library knows nothing about U++ Moveable
+	/// concept):
+
+	Array<std::string> as;
+	for(int i = 0; i < 4; i++)
+		as.Add("Test");
+
+	for(auto s : as)
+		DUMP(s.c_str());
