You initially said that rewriting in Rust "seems stupid" based on what Fil-C provides, and someone pointed out technical reasons why it still might be useful in some circumstances. It's great that a single dad is able to build Fil-C on his own, and you're certainly entitled to the opinion that you don't like the idea of lifetimes in the type system, but it's genuinely hard to tell if there's a specific technical point you're trying to make or you dislike Rust so much that you're interpreting someone disagreeing with you about whether Fil-C obviates it as somehow being a personal attack on the author.
