I almost feel stupid writing these long explanations, just to see them getting ignored ultimately. The automaton arrow is one of the most useful and most underappreciated concepts for state in Haskell.

While I'm not sure I have a need for it right now, I definitely haven't ignored this exchange---I've read the individual emails, and a link to the archive is filed away for future use.

So it's been very helpful, even if those being helped aren't participating per se.

+1 Because of those posts I spent my morning reading about arrows which seems a quite interesting concept, although couldn’t yet see what is best for ( I would be curious to learn it in order to try out Yampa). I have to say that the resources I found to learn about arrows on the net were a bit disorganized. This page is really well done http://en.wikibooks.org/wiki/Haskell/Understanding_arrows but then because I don’t know much about parsers I couldn’t really progress through the second half. best, Miguel Negrão
