g0xA52A2AA tail-call interpreter in (nightly) Rust
Finally! Tail calls! I had to write rust some years ago, and the ocaml person in me itched to get to write tail recursion.
Tail recursion opens up for people to write really really neat looping facilities using macros.
Rust has the become keyword now I believe for TCO.
From the first line of the post:
> Last week, I wrote a tail-call interpreter using the become keyword, which was recently added to nightly Rust (seven months ago is recent, right?).
