Every language tries to implement the best in class memory set/search primitives. Maybe we should move them to something called libos, where they will be implemented by every host OS? Then, OS manufacturers can supply libos.so/libos.dll/libos.dylib as part of the official OS distributions.

If the wheels get reinvented again and again, it means that they should be readily available.

There is an existing concept called an exokernel. Moreover, I think Zig could be very suitable for this, because it already encourages passing allocators to functions to make memory allocation explicit. Recently, I/O has been (and is still being) reworked in a similar way.

Isn’t this what libc is? Like musl-libc or glibc
