+Match patterns now use new dedicated AST nodes (``MatchValue``,
+``MatchSingleton``, ``MatchSequence``, ``MatchStar``, ``MatchMapping``,
+``MatchClass``) rather than reusing expression AST nodes. ``MatchAs`` and
+``MatchOr`` are now defined as pattern nodes rather than as expression nodes.
+Patch by Nick Coghlan.
