Hi Lyndon Are you just coalescing adjacent elements (if they are the same constructor)?
As it seems you have a list here rather than a tree, I'd step out of Uniplate at this point and just do a list traversal with direct recursion. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
