�Z d S ) � _PatternLista Match against a list of comma-separated positive and negative patterns
This class is a base class for building a pattern matcher that
takes a set of comma-separated positive and negative patterns,
returning `True` if one or more positive patterns match and
no negative ones do.
The pattern matching is done by objects returned by the
build_pattern method. The arguments passed in when a match
is performed will vary depending on what class build_pattern
returns.
