Mojo’s model looks interesting here. No GC and no ref counts, something akin to a reference count mechanism at compile time. Not sure how it works exactly and the documentation (as is the whole project) very alpha.
- lambda_garden 3y agoThe only way this can work in practice is restricting the memory patterns that the developer can use, which is what we see in Rust. Is it impossible to prove memory safety in the general case due to the halting problem?
- naasking 3y agoIt's possible to permit arbitrary memory patterns by adding ref counts in specific ways: https://www.microsoft.com/en-us/research/publication/perceus-garbage-free-reference-counting-with-reuse/ https://www.microsoft.com/en-us/research/publication/perceus... It's interesting how much there still is to discover in this space, despite decades of research.
