It's not really producing a whole separate language that I've found. There is a lot of functionality so the learning curve has been pretty steep to start. The macros are for pretty specific things but once you split out stuff like permissions, changes, etc you just use normal elixir modules. I can't think of any situation where I'd need to go outside of it and couldn't. It is built on top of all my normal elixir stuff and I've had no issue using them as normally. I'd definitely suggest reading the book first though there is a lot of unknown unknowns with it.
