The myth that 'Rust can do anything' collapses the moment you try to scale a recursive AST. For SQL parsers — massive tagged unions, deep recursion — Rust's type system breaks down in both compile time and maintainability. A 3-language benchmark porting the same parser to Nim and Roc shows exactly why Rust is structurally the wrong tool, with runnable code.
A technical look at Roc — Richard Feldman's pure functional language. Covering the alpha4-rolling status, Perceus reference counting, the Platform/Host model, and the Zig compiler rewrite, informed by AlopexDB's SQL parser trial.
