 DESCRIPTION
         Optional hooks to initialize a cloned object after creation.
-        Hook setting can be unbound lambda closures, or the name of
-        the function (static or public) to call in the object.
+        Hook setting can any closure, or the name of the function
+        (static or public) to call in the object.
 
-        If the hook is a closure expecting arguments, it is bound to the
-        current object and called with the created object as the first
-        argument and any further arguments from the clone_object() call.
-        If the hook is a closure without arguments, it is bound to
-        the object to be initalized and called.
+        If the hook is an unbound lambda closure expecting arguments,
+        it is bound to the current object and called with the created
+        object as the first argument and any further arguments from
+        the clone_object() call. If the hook is an unbound lambda
+        closure without arguments, it is bound to the object to be
+        initalized and called. If the hook is any other type of closure,
+        it is called with the created object as the first argument and
+        any further arguments from the clone_object() call.
 
         If the result of the closure call is a non-zero number, it is used
         as the interval to wait before the first reset(), else the default
