  Hello programmers,
  
  I have a problem to solve and don't have a clue where to start.
 
 This is a homework question.  Please read
 
 http://www.haskell.org/hawiki/HomeworkHelp
 
 for some helpful hints.
 
 By the way, you shouldn't post the same message to multiple lists - you should 
 choose the right one (haskell-cafe in this case), or if you must, cross-post one 
 message to both.  This means people who subscribe to both won't see your message 
 twice.

RE: automaticly create the ana, cata, hylomorphisms

[Marta Isabel Oliveira]

Ok, i read the page but i'm still stuck.

I'm reading some papers about cata,  ana and hylomorphisms but i need to know where to 
start putting it to code.

So,

1. in order to have a pre-processor, i need to have a module with ALL data types?
2. from this module, how could i create the cata, ana,...

i mean,

a)how can i represent the result in haskell
b) how can i create the cata(whatever) without knowing all of the possible functions 
that may be inserted in order to it's cata be created?

thansk a lot,

lesina.
