[INFO] [stdout]     = note: reference of mutable static is a hard error from 2024 edition
[INFO] [stdout]     = note: mutable statics can be written to by multiple threads: aliasing violations or data races will cause undefined behavior

[INFO] [stdout]     = note: this warning originates in the macro `built_in_classes` (in Nightly builds, run with -Z macro-backtrace for more info)
[INFO] [stdout] help: shared references are dangerous since if there's any kind of mutation of that static while the reference lives, that's UB; use `addr_of!` instead to create a raw pointer
