If it's the right solution then an experienced Haskell developer will congratulate you. If it's the wrong solution they'll point you towards a functional solution which likely works better with the language/paradigm.

That was intended as a joke, but not completely. Emulating OOP seems to be deeply frowned upon by Haskell developers.

That is, until you actually do it; I don't think I ever saw people complaining about any actual instance of OOP-like code, just about the idea.

Are you sure? I don't think many frown upon the Yi developers for it:

Sometimes there is something to complain about ;)

I remember listening to a Haskell Cast with Michael Snoyman and/or Gabriel Gonzalez of the Conduit and Pipes fame... whoever it was mentioned that their early designs were very imperative because they thought it was necessary for performance.

However over time a functional API/core emerged and was more stable and performant.
