There is a simplified version of HList style functionality inside
HAppS-Data because I found Oleg's repo too hard to understand.

Just wondering if I missed anything, or if any of the ideas
considering better records setter/getters have been implemented in the
meantime.
Have a look at [http://code.haskell.org/category], and the associated blog posts
http://twan.home.fmf.nl/blog/haskell/overloading-functional-references.details
(http://tinyurl.com/2ustba)
and
http://twan.home.fmf.nl/blog/haskell/References-Arrows-and-Categories.details
(http://tinyurl.com/2v8het)
which discuss "functional references" (similar to Luke's), and include
Template Haskell code for deriving more flexible accessors from a
record declaration.
Also check out HList [http://homepages.cwi.nl/~ralf/HList/], which can
do some interesting things, provided you're willing to abandon the
built-in record system.
