+# Visitor
+
+## Purpose
+
+The Visitor Pattern lets you outsource operations on objects to other objects. The main reason to do this is to keep a separation of concerns.
+But classes have to define a contract to allow visitors (the `Role::accept` method in the example).
+
+The contract is an abstract class but you can have also a clean interface. In that case, each Visitor has to choose itself which method to invoke on the visitor.
