Buildkite-style moaning

[RazvanN7]

LOL. What was the point of it? Was this an accident?

[MoonlightSentinel]

Probably, it was introduced at the end of the file just before a version(none) declaration.

__EOF__

[schveiguy]

I just was about to create a PR to remove this.

I found it in my attempts to refactor phobos for phobos v2, my refactoring didn't do well with this. @MoonlightSentinel was on the beerconf call when I found it, thanks for fixing it!

Was this an accident?

I actually emailed Andrei, and he said he remembered some compiler bug making him put something like that in.
