Not until JVM supports value types, low level pointer manipulation and reiffed generics.

2 out of 3 of those are coming in Valhalla. You don't need pointers.

If you want to support F# without performance degradation emulating features, I am not so certain.

In addition to that, the .NET runtime supports tail calls but the JVM does not, IIRC.

Yes, JVM still has it under "some day it would be nice".

Actually this is one of the bytecodes that .NET Native doesn't handle, if I am not mistaken.

Yes, but it wouldn't be F#. F# is so deeply tied to .NET semantics that you'd have a very different language, even if the syntax looked the same.

JVM has already got clojure, scala and kotlin.
