[Haskell-cafe] HList and Type signatures / synonyms

I keep accumulating values and right now use plain tuples for that. I end  
up with a 12 element tuple and things are a bit messy.

I'd like to use extensible Records from HList instead, thing is I'd like  
to keep putting type signatures in my code. As it turns out that seems to  
be where it gets messy with HList.

Is there a simple way to do this?


PS: Does anyone know why there are Label-n modules in HList, and which one  
to use?
