Hmm. I see. And I see that you are correct in not seeing it, since it appears it cannot be done with Happy, which I believed. It would then be down to the parser/lexer to pass on unconsumed input, which seems a daunting and disruptive task, seeing how the lexer typically would tokenize some input in advance before the parser discovers that it cannot consume what has been lexed... Hmm. I still find it a highly desirable feature, and at some point I would like to give it some further thought, to see if a way can be found. In the mean time, would you mind filing a feature request at http://trac.haskell.org/haskell-src-exts ? Cheers, /Niklas
