> KDAB is now running clazy over the Qt code base, you can check the results
> here: https://ci.kdab.com/~build/analysis/qt5/clazy.html

> Next step is to figure out which sub-set we want to use in within qt-project,
> if we want to enforce any via CI, which ones we want to fix for Qt5 and which
> ones for Qt6.

> I'll try to propose something soon, and probably focus on the checks that
> reveal real bugs, leaving the performance stuff for later.
