+class PseudoKeyword:
+    """A callable class that calls a method passed as a parameter.
+
+    Good for creating a pseudo keyword in the python runtime
+    environment. The keyword is really an object that has a repr()
+    that calls itself which calls the method that was passed in the
+    init of the object. All this just to avoid having to type in the
+    closing parens on a method. So, for example:
+
+        >>> quit = PseudoKeyword(SomeObject.someMethod)
+        >>> quit
+
+    SomeObject.someMethod gets executed as if it had been called
+    directly and the user didn't have to type the parens, like
+    'quit()'. This technique is most applicable for pseudo keywords
+    like quit, exit and help.
+
+    If SomeObject.someMethod can take parameters, they can still be
+    passed by using the keyword in the traditional way with parens."""
