As a concrete example, here is a video (and github link) of a concrete program that I'm currently working on, and that I think is not a bad program. https://vimeo.com/605017327 https://vimeo.com/605017327 I already have plans for improving it (especially the layout system), but overall it works pretty well and is reasonably featureful with little code. It's not perfect but "state" is certainly not a problem at all. I can't tell you something like this can't be coded in maintainable Haskell, but I can tell you that _I_ wouldn't have managed, and googling around it doesn't seem like there are a lot of people who can do it.
