Hi. I noticed pull requests which add comments to test cases (class comments). I guess the reason is that in Calypso uncommented classes are marked differently than in Nautilus and the exclamation does not disappear when class provides special icon like status of tests. So the question is do we really want people comment test cases? I did not notice any meaningful comment from those PRs. It's like "Unit tests for mirror primitives" for MirrorPrimitiveTests (case 22207 <https://github.com/pharo-project/pharo/pull/1598>). Personally I don't like such approach to put class name with spaces in the comment. It is useless and duplicated. Alternatively I can change uncommented mark to be like in Nautilus. But I like Calypso approach because #systemIcon is not overridden by exclamation. If we want to keep it we need to introduce some #requiresComment to Class which will be overridden by TestCase. So what you think?
