-// FEATURE: serialization of ParseTable's, generation of Java code
-// FEATURE: infer reject elements for literals
-// FEATURE: prefer whitespace higher up
-// FEATURE: full conjunctive and boolean grammars
-// FEATURE: "ambiguity modulo dropped fragments"?  can this be checked for statically?  eliminated statically?
-//            - drop stuff during the parsing process (drop nodes)
-
-// LATER: Element<A> -- parameterize over the input token type?  Makes a huge mess...
-// LATER: Go back to where Sequence is not an Element?
-//            - The original motivation for making Sequence "first class" was the fact that 
-//              in order to do associativity right you need to have per-Sequence follow sets
