A few weeks later Jana and Mara implemented a fourth solution, which has no RFC. And realized that Rust already have Externally Implemented Items (EII). One of those is the Panic Handler. When building, the core expects a function to be marked #[panic_handler]. With std there is one already provided. The second one is the Allocator, which is a trait with four functions that also needs to be externally implemented. #RustInParis

For their implementations, Mara and Jana decided to have a core definition that is empty but shows the type. It has an attribute to be used to decorate the external implementation. It allows separate implementation and name resolution. #RustInParis
