Why does zig purposely fail on windows text files by default? Do you really expect a language to catch on when you are purposely alienating windows users by refusing to parse \r for some bizarre reason?
I find it hard to believe that someone could be capable of writing a non-trivial program but not able to change their text editor settings to use \n.
I'm floored that so many people would ignore this barrier to entry and somehow rationalize such a ridiculous design choice. If you make things straight up break for all windows users by default in your new language, it's going nowhere. No rationalization or excuses will change that reality.
How many developers who try out new languages are even using Windows? I'd imagine most are on a UNIX-like. Regardless, I don't think it's a big deal either way. You could always make a merge request with a fix if you feel so strongly about it.
