Hi!<br><br>I am a novice in Haskell, and particularly I have interested in generic
programming. This interest motivated me to read paper Scrap your
boilerplate: A practical design pattern for generic programming,
but I didn&#39;t understand the type of the function gfoldl, that was present in class Term (Data). Somebody could help me to understand
the type of this function?<br><br>Thanks...<br><br>Rodrigo<br>
