Thanks Eric and Brent,

Even with GADT, it appears that I'd need extra data definitions. I'll go

without GADT then ...

Brent, my use case is not particularly complicated. I am trying to model

the pdf spec - which says that pdf contains Objects that could of of types Number, String, Name, Array and Dictionary - while array is list of objects, the Disctionary is a list of tuples (Name, Object) not (Object, Object) - hence my situation.

You could have a look at how the aeson package represents JavaScript values, which have a similar structure to your requirement, e.g. http://hackage.haskell.org/packages/archive/aeson/0.6.1.0/doc/html/Data-Aeso... Doug
