I’m sorry, but I still don’t understand what you mean. Haskell has mature libraries for writing web services. That’s what I use the language for, and it’s hardly a niche.

Plenty of people (including some of my colleagues) write Haskell in Visual Studio Code.

I don’t know anything about Tensorflow (though machine learning seems a bit more “niche” than building websites tbqh), and I haven’t known anyone to use Eclipse for writing code in the past decade or so.

Genuinely, I haven’t a clue what you are talking about. How would three general purpose languages “work out of the box” with X, but a fourth would not? Eclipse is a text editor and you can write Haskell with it. There are Haskell bindings to Tensorflow available.

Your point now doesn’t even seem to be consistent with your original point. How is Eclipse state-of-the-art? How is Haskell behind?
