You might be interested in Oleg's paper Haskell's Overlooked Object
Systemhttp://homepages.cwi.nl/%7Eralf/OOHaskell/code.html,
although programming in an object-oriented style is neither elegant nor
idiomatic Haskell. Aside from the actual embedding of an object-oriented
language inside Haskell, the main benefit of the paper is the opening survey
of approaches to object-oriented style programming in Haskell. Not
surprisingly, however, encapsulation and subtyping are the most difficult
concepts from object-oriented languages to capture with Haskell type classes
and algebraic data types.

Thanks Antoine,
Is there a particular problem you're trying to solve? we might be able to take the conversation in a less speculative direction.
At this point its academic ... I have programmed in OOPS for a long time so, I just wanted to understand how one would go around something like that in Haskell.
I came across something called the expression problem and it talks about "open data type" - is this the solution?
Regards, Kashyap
