I familiar with Scala, Rust, and Haskell from this list, though I didn’t program on any of these practically. The list of languages I learned to some extent includes may be 10–15, though most of them aren’t truly functional (F#, Scala, Kotlin are the ones I at least played with).

As for the response, I think you must be more explicit with the feedback. It’s totally unclear why your comment invalidates any of my points :)
