I realise this is probably my issue, but I'm getting an error on composer install since this file was moved.

It's only failing in CI (i.e. a fresh build with no cache or anything). On my local machine it's fine. I'll post back if I figure it out.

As is often the way, and as I suspected, the issue was mine, and I solved it moments after posting the above :joy:

There was another cache at play - the CI runner cache on GitLab. After clearing that, it built fine.

Hopefully this helps someone else!

@driesvints is this class aliased anywhere? The SupportArr test still references the old path but I can't seem to find any aliasing that would support that.

[driesvints]

Hey @LukeTowers, what do you mean with

The SupportArr test still references the old path

Can you point out where?

[LukeTowers]

@driesvints sure, see https://github.com/laravel/framework/blob/8.x/tests/Support/SupportArrTest.php#L6

[driesvints]

That seems okay to me?

[LukeTowers]

@driesvints it's referencing lluminate\Support\Arr when the actual class is lluminate\Collections\Arr. If lluminate\Support\Arr is expected to work; my question is where is that connection between the non-existent lluminate\Support\Arr class and the actual lluminate\Collections\Arr class set up?

[driesvints]

The Illuminate\Collections namespace doesn't exists?

I do see there's two usages of it that was introduced in this PR but the OP accidentally used it while it should have been Support. I'll send in a PR to fix that.

[LukeTowers]

@driesvints ahh, I see! The collections stuff was split off into its own package but the namespace remained the same; that's the critical piece of information that I was missing. Specifically to answer my own question this line is what makes /src/Illuminate/Collections/Arr.php available as Illuminate\Support\Arr.
