Description
It was observed in a rule like:
((chunkType{-PARTOF(Enumeration),-PARTOF(ChunkCombineBlocker) -> Member} SPECIAL.ct=="-"? COMMA)* chunkType{-PARTOF(Enumeration) -> Member} SPECIAL.ct=="-"?{-PARTOF(chunkType)} COMMA?{-PARTOF(chunkType)} @EnumIndicator{-PARTOF(Enumeration)} chunkType{-PARTOF(Enumeration),-PARTOF(ChunkCombineBlocker) -> Member}){-> Enum()};
Between EnumIndicator and the first left chunkType, several chunkType are skipped.
