Haskell does not have OOP facilities built into the language. But then, Haskell arguably doesn't have sequencing of IO built into the language. Standard libraries get the latter done, in many ways better than it's done in other languages. The former lacks a canonical representation provided by any standard (or nearly standard) library I'm aware of, but it's pretty easy to implement the pieces you need yourself once you're aware of the patterns.
