I have a few large React apps that have been using mostly Immutable.JS from the very beginning, so I rarely run into issues where I need to think whether what I'm dealing with is an Immutable.JS object or plain JS objects. I can see an issue if you are incrementally converting an app to Immutable.JS and dealing with a mix of plain JS objects though.

I have heard criticisms of lisp macros as making it a write-once language. If you're not working on a team then maybe it's fine, but other people aren't gonna want to figure out how your macros work.

This is why a professional developer needs to document their code. If they don't do that, then they are NOT a professional.

Plus they are selling themselves short. If you want to fully learn something you must teach it. By documenting your code you are teaching the other developers on the team and this will lead you to much deeper understanding than the hackers who churn out code all day.
