Not a problem at all. Our project is very data heavy and we define
lots of one line methods, so we have made good use of them.

Sure. I tried a few things and the only problem I can find is that it
does not handle endless module methods:

def self.some_method =
  "some-value"

(with or without the line break, it handles them as the unpatched
version handles instance endless methods.

Sure thing, just sent one in: bug#60110

Yeah, this is what I see too. Not sure what I saw before. In any case,
I sent a current/desired.

Copy that. It works well for me. My endless method patch has since been merged.

Unrelated, but I'm excited about the prospect of a treesit mode for Ruby.

Thanks again,
