Difflib.SequenceMatcher object currently get two feature attributes:
self.isbjunk = junk.__contains__
self.isbpopular = popular.__contains__
Tim Peters agrees that the junk and popular sets should be directly
exposed and documented as part of the api, thereby making the functions
redundant. The two functions are not currently documented (and should
not be now). A google codesearch of 'isbjunk' and 'isbpopular' only
returns hits in difflib.py itself (and its predecessor, ndiff.py).
It would be easiest to just remove the two lines above.
Or should I define functions _xxx names that issue a deprecation warning
and attach them as attributes to each object? (Defining instance methods
would not be the same).
There is only one internal use of one of the two functions which is
easily edited.
