Max Brunsfeld 7a2c2c1c90 Store ParseItemSets as maps, w/ core items as keys ... ParseItem no longer has a lookahead_sym field; it now represents the 'core' of a parse item. The lookahead context is stored separately, as a set per core item. This makes iterating, copying and merging item sets more efficient, because before, the core items were repeated for each different lookahead symbol. Also, the memoization in sym_transitions(ParseItemSet) has been removed. Maybe I'll add it back later.		2014-06-16 08:35:20 -07:00
