A trace function should return a new trace function or None.
Class methods are accepted (and most useful!) as trace methods.
The global trace function is invoked (with \var{event} set to

The local trace function should return a reference to itself (or to
another function for further tracing in that scope), or \code{None} to
turn off tracing in that scope.
Instance methods are accepted (and very useful!) as trace functions.
