This looks to me like one of the HList-based record systems.  But that could
get you into hot water fairly quickly, as while the record/lens packages try
to cover up the ugliness, it's all based on some fairly complex type
hackery.

http://www.haskell.org/haskellwiki/Extensible_record is an overview of the
field.
