BNF grammar parser


Marpa::R2 parses any language whose grammar can be written in BNF. That includes recursive grammars, ambiguous grammars, infinitely ambiguous grammars and grammars with useless or empty productions. Marpa does both left- and right-recursion in linear time -- in fact if a grammar is in any class currently in practical use, Marpa will parse it in linear time.
