I remember - this makes the change from Maybe to Either very easy :) Still I found that adding 
error message to every combinator and function ads a lot of boilerplate. Also, I experince 
problem with granularity of the messages, e.g. a message like "digit expected" is too low-level 
not helpful without telling user that the problem was in the incorect date format.
