Empirically, there are a lot more million line python codebases than F# or haskell codebases, in fact I can name multiple million line python codebases, and 0 F# or haskell codebases. Given that, logic would indicate some sort of failure on the part of haskell and F#, or they would see wider adoption among the large codebases where they are so useful.
Given how much smaller is the F# community and how much more you can crank in less lines of codes in F# I can believe it.
Between C# and F# there is about an order of magnitude of difference in the LOCs for big projects and C# and Python are comparable from this metric.
It appears you missed my point. I can't think of a 100kloc f# or Haskell codebase, so even if they were 10x as terse as python, which they aren't, python comes out ahead. If they're so much better, why don't people use them?
I can think of 100kloc Scala codebases, e.g. Kafka.
People do use ML family languages, and they are better. There are plenty of non-technical reasons they aren't as widespread as dynamic languages or shitty static languages.
Do you disagree?
