The problems you had or still have with ML and Haskell are probably mostly about pure syntax. For beginners, syntax matters a lot. Over time, we get over it, and learn to see the underlying structure of the code. About the deeper problem of "thinking in OOP", I wrote a small tutorial[1] about the first step: avoiding mutable state where you can help it. The second step is to remove loops (even the recursive loops as well). Instead, use `map` and `filter` (the bulk of list comprehension) where you can. The final step is to generalize this approach by writing your own "higher order" functions to capture common patterns.
