test case? also pre-commit has failed

[Bolpat]

@thewilsonator, I added a test case. I have no idea why the pre_commit previously failed.

Another thing I noticed is that on my DMD PRs, circleci quite consistently fails on some _Complex!float and friends. Is that normal or can I do something about it?
