I like Haskell more than Clojure, but I don't know much about lenses and traversals myself either.
The reason I came to like Haskell is that they tend to ground things in (type/category) theory, which gives you extremely strong foundation (the downside is that sometimes things get so abstract that it's really tough to understand them).
I don't disapprove the Clojure (and Lisp) approach of experimentation with new features, rather than trying to figure out the theory, but it can lead to unforeseen problems where you make design mistakes that are not obvious at the first sight.
A good example is a recent discussion https://news.ycombinator.com/item?id=18565826 about Maybe. There are several good arguments in the thread against the union types, which are very easy to miss at first glance.
So, I would recommend you dive into the theory of Lenses and Traversals, to see if you can avoid some mistakes you're perhaps doing (AFAIK there are several different definitions of lens in Haskell). As they say, a month in the lab can save you an afternoon in the library. Although I agree that lab is much more fun!
