Visual studio does it for C#, at the very least. Other formatters choose other options, and it's a matter of preference in any case (I personally think it's a code smell to have that many arguments or that long of names, and I also don't limit myself to 80 columns, cause I've got a widescreen monitor)

Either way, it's a trivial algorithm to implement. Calculate len("function_with_lots_of_arguments("), add that many spaces after your indentation tabs on the next line, continue arguments. The fact that editors/auto-formatters don't do that speaks far more to their lack of desire for that code style then it does to the difficulty of doing it.

The simple fact remains that using tabs provides many accessibility benefits that spaces are just unable to provide, like being able to drop tab size when you boost font size (legibility for poor vision) so your code doesn't indent off the side of the screen, or far better support for indentation for proportional fonts (another thing that people swear by for increasing legibility).

Just to be clear, I prefer tabs over spaces myself, so I'm not arguing against tabs. What I'm arguing against is mixing tabs with spaces, with the expectation that every contributor to the codebase uses sufficiently smart editors to not break the formatting.

With that out of the way...

That breaks for `foo(bar(a,\nb,\nc))`

And if you fix it to be "len till the last unmatched (" then it breaks for `foo(bar(a,\nb),\nc)` because the two lines have to indent to different levels.

Just saying it's not as trivial as it seems.

And is a reason to not use such a style in the first place, as I said.

That's still just an argument for "everyone use a specific formatter with these settings". Go's formatting is simple, built into the main implementation, and has no knobs, as a result, everyone uses it, and all code is formatted with tabs and spaces. It can work, esp. if a language adopts it early (like Zig could have).
