I enjoyed using it for gap-mode [1] once I got the hang of it, though I would hesitate to suggest that people should look at my implementation. :-)  And I love, love, love the sexp-based movement it gives me for free.

I took up this project (https://github.com/elixir-lang/emacs-elixir) just a couple months ago, so I thought the convolution of the code I replaced was a result of SMIE. I was skeptical about the degree to which I would be able to simplify the logic.
