Probably shouldn't use console, but idk.

Looks good to me otherwise.

We REALLY need to deprecate those broken packages.

[BendingBender]

@ZaneHannanAU the broken package is a really strange one, it only breaks on typescript@next. This looks like a bug in the compiler, not in the package definitions.

[Flarna]

Well, unist-util-is is just two days old so maybe a bit early to deprecate it 😁.
I asked the author in #31084 what's wrong as CI was green there.

[ZaneHannanAU]

… I think, at this point, we should have the CI check every package and not just what has been definitely effected.

But then that'll take forever.

… ugh, there're gonna be too many damn edge cases.

@Flarna I'm leaning towards a TS change as the cause, but I'm still investigating (cc @Rokt33r).

[amcasey]

Changed my mind - I think the test is wrong. I'll follow up on the other PR (and try to determine why the CI didn't catch this).

[Flarna]

@BendingBender uninst-util-is should be fixed by #31257. You could try to retrigger CI, hopefully it's green now.
