[Haskell-cafe] A generics question

[Stefan Holdermans]

Henry,

Ah, pressed send way to early. Of course, the definition should change  
a little as well:

  convert :: Data a => Int -> a
  convert i = x    where
      x = fromConstr ( dataTypeConstrs (dataTypeOf x) !! (i - 1) )

Cheers,

   Stefan
