The recent decision by Roc to rewrite its compiler using Zig instead of Rust has stirred discussions among developers regarding the choice of programming languages for compiler development. Many commenters expressed skepticism about Rust's complexity and long compilation times, advocating for Zig's simplicity and pragmatic approach. Roc's commitment to using LLVM for compatibility and efficiency has been highlighted as a major advantage. There are concerns regarding the trend of favoring libraries over protocols, which could hinder independent implementation. Moreover, the organic nature of Roc's transition, devoid of external pressures, has been noted positively. Overall, the transition to Zig appears to be a well-reasoned strategy aimed at enhancing performance and maintainability, sparking dialogue about the future of programming language design and usage in the compiler context.
