Now I can refer to each value by name, and I also can easily iterate over the table P.

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. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
