+objects, which are callable objects that are meant to be optionally replaced.
+The idea is that you create a function that does some default thing and make i
+hookable.  Later, someone can modify what it does by calling its sethook method
+and changing its implementation.  All users of the function, including those
+that imported it, will see the change.")
