@joa-quim In response to https://discourse.julialang.org/t/ismissing-x-versus-x-missing/52171/3: That’s why I’m working ShowLint with the possibility to disable lint patterns in bulk. Instead of adding a lint configuration to each project/repository, I could just disable the check for this pattern and similar checks on all “high-performance” repositories. Basically, the idea is that all the configuration complexity is moved away from the user and is managed at one place. Also, the idea is that its easier for the Julia community to help busy package creators out. For example, some packages are created one or more years ago and the creator has moved on to other things. With something like ShowLint, the community can more easily assist these creators in keeping their packages working and up-to-date.
