As an intermediate Haskeller I'm curious, what's the replacement for SYB? I've worked in haskell primarily on compiler-like tree tranformation code and SYB seems to fit the bill perfectly.

The direct equivalent and replacement is GHC http://www.haskell.org/haskellwiki/Generics.

Edit: I just wanted to add that if you do compiler-like tree transformation code it behooves you to explore uniplate/multiplate/plated.

Sick, thank you for the reply and pointer to uniplate and associated tools!

IIRC, the thing about Uniplate is that the API makes it easy to build traversal functions like "get a list of all X nodes in this tree" while SYB provides some folding operators that are a bit harder to work with.

There's http://www.haskell.org/haskellwiki/Template_Haskell, for one

TH isn't really the same functionality as SYB.
