+1 on that, I use uniplate for pretty much all my haskell-src-exts tasks
these days, works like a charm!

I'd love to include some standard traversal functionality in
haskell-src-exts that depends on uniplate, but hesitate to do so because of
HP aspirations for haskell-src-exts. Neil, what do you reckon the chances of
getting uniplate in the HP are? :-)
