Every couple of months, I think to myself that I ought to buckle down and make an effort at really learning Haskell. And I go through some books and some toy projects, and then I hit the wall. The problem is, I can't actually use Haskell in anything production, because nobody else that I work with is going to be able to figure out how it works, and if I move on to some other job, my employer is never going to find somebody with Haskell experience in this area - at least for what they'd be willing to pay. F# looks like a more pragmatic choice, and I've been looking hard for a good place to bite off to use it going forward. But again, it'll be bad for the bus factor. So the best option I've found is to just start using more functional concepts and patterns in Java/C#. C# in particular seems to be leaning in this direction with the features added in the latest language versions.
