Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-06-15 10:35:49 UTC
Introduced by https://invent.kde.org/graphics/spectacle/-/merge_requests/321.

There's a comment in the code at https://invent.kde.org/graphics/spectacle/-/merge_requests/321/diffs#5589a1428daea5581737b23942331eabe5a362b8_0_184:
```
    // reinterpret_cast can be dangerous. It's like telling the compiler to
    // act like this type is another type regardless of whether or not they're really compatible.
    // List and ConstList should be compatible. ConstList's only difference from List is that
    // ConstList has a const value type.
```
