Re: [Haskell-beginners] general comments requested

Hi Michael It looks fine - with one big exception. Tracking down /undefined/ can be quite tedious, there is no indication at run time which particular undefined signalled the exit - I'd recommend you always throw an error with an identifiable string. Also, I wonder if the the MusicXML library on Hackage was auto-generated at least in part? It would be nicer to work with if it used constructors and field-labels more, rather than long tuples; though there isn't much you can do about that. Best wishes Stephen
