One recurring theme about these new wannabe C and C++ replacements, but not like Rust, is that their solution is basically to use what already exists in C and C++ for the last 30 years, if only people actually bother to learn how to use their tools.
Unfortunely it is a bit like debugging, lets keep doing printf(), instead of take the effort to learn how to use better approaches.
It’s also something allocators commonly implement already.
