Hi Mike Thanks - indeed, I was just looking up the thread that covered them a month or two ago: http://www.haskell.org/pipermail/haskell-cafe/2009-December/071392.html I wouldn't recommend writing code that depends on Data.Aviary, but some of the combinators are often worth copy/pasting out of it. Best wishes Stephen
