A language could be declaered good enough but none of the popular languages are there. They all had plenty of "bad but popular" design decisions at the beginning and now they are trying to compensate. What I hate is the constant repeating of everything. I'd rather one language have everything crammed in and we get to choose what we want and what we don't want. No "good" (my opinion) language will ever have only "one way of doing things" so why not just add everything and get over with it. In any case, all the "big" languages seem to be racing to "add everything" anyways.

IMHO my biggest issue with languages like F# and Haskell is like you mentioned the lack of tooling. I can even get over the fact that the ecosystem is smaller but the lack of ergonomics (things are harder to do, there's more friction in the dev process) always sends me back to C#. I wish F# tried to get into Roslyn instead of having their own compiler. I get the prestige and practicality of doing your own thing but I think it costed them a lot of missed out features and polish. I'm not that familiar with F#. It very well could be the language is too different to reuse almost anything from the semantic part of Roslyn but there's still so much else there they could get for free
