I think the fact that this (and all macros with `babel-plugin-macros`) requires an explicit import helps keep it out of magic territory. You do have to become aware that the symbols transform the function/argument they're a part of, but this is only really new to JS devs. It's familiar in a bunch of other languages.

I documented how they work in this part[0] of the readme.

The import tells you that some of the expressions in a file might be functions, but not which ones. For each definition, you have to read the entire expression to tell whether it's a function or evaluated immediately, and what its arity is. No thanks! Reading the entire file just to find out its API is no fun.

I like the direction typescript is going, where you can easily see not only the arity but the type of each parameter, without reading the function body. This is more skimmable.
