The Trifecta Tech Foundation has proposed a project goal to advance explicit tail call optimization in Rust, aiming for potential stabilization in 2027. Tail calls allow function calls to reuse stack frames, enabling safe recursion without stack overflow risks. The initiative seeks funding support and introduces the 'become' keyword syntax for explicit tail call declarations.
Background
Tail call optimization is a compiler technique that allows recursive function calls to reuse stack frames, preventing stack overflow. While common in functional languages, Rust has been discussing but not yet stabilized this feature.
