I think it's mostly about good taste on what you define functions to take as ref input. I have a feeling the present way is not a big problem in practice because it is intuitive somehow. Besides, member functions mutate their class/struct anyway, and we don't want to lose our ability to call extension funcions with same syntax as member ones.
well for the extension functions I wrote that if the ref parameter is the first argument and it's called with ufcs syntax, it could implicitly add the ref probably. I don't think there are any big issues with that, it does look like a member function and the programmer could easily read it as "this modifies it"
