Sorry about the confusion.  By bound method I meant the callable
obtained by binding a method (built-in or written in python) to a
concrete instance, as opposed to an unbound method, such as
list.append.  The reprs are different for built-in methods and for
python methods, but I consider that difference an artifact of the
CPython implementation, not a distinction mandated by the language.
