The Haskell learning curve - including the wonderful range of useful
generic stuff you can do with it - extends way higher than for many
other languages, I think, though you can write lots of useful code when
you're just partway up. I'm still learning things, and knowing I have
much more yet to learn, and normally I can learn most of my way around a
new programming language within a couple of weeks.

http://www-users.cs.york.ac.uk/~ndm/uniplate/ may help to answer that
question. I haven't even finished understanding SYB, yet, though; I'm
still mystified by how to use Data.Generics.Twins.gzipWithQ. So, I'm
not at a stage where I can usefully contrast Uniplate with the
Data.Generics stuff.
