Overwritinggroupflags

Hello.

I'm working on a project that has several smaller Rust projects and wanted to add every possible lint or lint group to them so we know exactly what's still there to fix and know exactly when something bad is introduced. I should note that these smaller projects are not in a workspace.

Using the typical

for a group and then

another lint inside it is what I wanted to do initially, but also having rustc lints in that list quickly bloated it to about 45 lines. And managing this list in every small project is pain. So I ended up writing a small script that can be run from inside the CI and by developers alike without having to manually update all

or

files every time a new lint can be

'd.

When running the script it turned out that all of the lints in groups that were on

suddenly popped up again even though they were

ed.

For example:

still triggers the

lint. Using

works flawlessly.

This was tested with

and pretty much forces me to fill 4 lib.rs/main.rs files with about 45

and

-s.

Is there a reason a

flag does not overwrite a

flag? If so, why?
