[Elixir 1.15] ** (MatchError) no match of right hand side value: {1, {:error, :no_cache}} about cachex

I managed to reproduce this, have a feeling it's related to OTP more than the Elixir version (unless it's somehow a bug in Elixir, because they shouldn't have broken the interface in a minor release).

I'll investigate further!

Okay, I'm fairly confident this is only showing up during tests, I don't think there's a "real" bug here.

It seems to be that the Janitor is not being closed properly when ExUnit exits; it's some sort of cleanup issue in tests that somehow only became a thing in Elixir v1.15+.

Ah, never mind - I found the issue and filed #321.

I guess older versions of Elixir were just masking this issue, but it's a legitimate bug (in the tests). I've fixed it and this shouldn't happen anymore.
