Number of "Clojure" results is 109, compared with 98 for "Haskell", for instance (in London, according to indeed.co.uk). So both are not scoring big, certainly, but those numbers are nevertheless better than 3-4 years ago.
Can you share (some of) the reasons for that decision?
...of course, for the other team to be able to do this, they still needed to learn some Clojure in order to understand our code, but even in the cases where they actually liked doing Clojure, they were still forced to do the rewrite. The company was/is expanding very rapidly, so part of me can understand the decision to narrow it down to fewer "allowed" languages, to allow services/responsibilities/teams to move around more freely.
But it was one of the main reasons I decided to leave the company. I had joined after years hoping for Clojure to be my main professional programming language (for a substantial part of my career, at least), and I left a somewhat more bitter developer, but at the same time feeling a bit more free and relaxed - there are sooo many opportunities to pick from, now what I'm a bit more open when it comes to the tech!
OCaml can embed or be embedded in native applications, but that's not the point.
I think that the main problem with Clojure is the lack of types.
Just look at how much Scala is more popular than Clojure, although it's also a strange functional language derived from OCaml/SML.
There is a common opinion that types are a necessity, even ruby, racket and python are adding them. Clojure people are just trying to substitute types with a runtime evaluated contracts/Hoare triplets, which is not an adequate substitution.
