A macro-based PEG parser generator for Scala 2.10+

The following code ``` scala def f: RuleN[Int :: Int :: Int :: HNil] = ??? def g = rule { zeroOrMore(f) } ``` results in the following error: ```...
When a rule transforms the value stack (rather than simply pushing values onto it) then these transformations are not always rolled back (as one would expect) when an `optional` or...
