The semantics are very close if not exactly identical. But it definitely feels and works as a separate language, mostly by having its own standard lib and toolchain. It's not ruby syntax either. There are some very obvious inspirations, but it also explicitly rejects some standard ruby moves in favor of FP conventions. The whole "ruby for beam" angle was dropped years ago, and I'm not sure how much if any support that marketing tactic ever had from the official elixir devs.
