LGTM after the tests pass. Curious to know if the cyclic reference error was fixed(and how), or we just compile files in different order now.

[nicolasstucki]

This was a bootstrap issue, we did a lot of improvements since it was blacklisted.

[DarkDimius]

@nicolasstucki CI disagrees with you.

[nicolasstucki]

@DarkDimius I ran all the CI tests on my machine before sending this PR. I will have to double check :(

[nicolasstucki]

@DarkDimius my machine disagrees with CI. Again...

[DarkDimius]

@nicolasstucki, different order of files? One of the reasons whitelist existed before is that it also provided a specific order of files.

[nicolasstucki]

I will try adding an order to the files. One that does not depend on the filesystem.

[DarkDimius]

@nicolasstucki I propose to order not by the file name, but instead by class name.
The reason is due to way people report bugs. They rarely post file names.

[smarter]

We already have some code to order by filename, but I guess it's not used everywhere: #2193
I'd like to keep ordering things by filename because I have at least one test which relies on it.

[nicolasstucki]

Will close this PR for now. This is not a priority.
