Dot-star file extension is a bit of a weird one and doesn't seem to be used outside of the cosmo-lang examples folder (search link). .cos seems to have a lot of junk (search link) - what would be a way to narrow down which of those are actually Cosmo? Any certain keywords that uniquely identify it?

[R-unic]

yeah i noticed that shortly after posting this. so the only keywords i could imagine would be unique to cosmo in a .cos file might be fn, from, until, unless, is, in, or mut. you could also use the function name puts. i'm aware all of those keywords are present in other languages, so the only keywords universally unique to cosmo are every and $.

i very much appreciate your time in considering to add cosmo! thank you for all you do <3

I bet true .cos files are getting close to 2000. Here is a search for path:*.cos fn with ~1.4k. And when you use other keywords like stream, you can tell there are .cos files floating around without the fn keyword. As for .⭐ there are only 15 files at the moment. And according to #5756, each extension needs at least 2000.
