The problem with F#, Clojure and Elixir (hosted languages)

For F# , you need some basic C# knowledge For Clojure, you need some basic Java knowledge For Elixir, you need some basic Erlang knowledge

I like all 3 languages but usually each vm have a primary language, and each hosted language eventually become hosted on that primary language not the vm

I understand that for many task simple, to medium complexity, you might not need that, but it seem as you try to be more advanced you hit the wall of having to learn you host vm primary language
