I’ve managed to port my quantum circuit optimizer (Rust) to Lean, along with a proof of correctness. Still significantly slower than Rust, but provably correct :)
Pretty wild that such projects used to take years and now they take just a few days.

My student Stavan Jain ran a Lean tutorial. After seeing how many people accepted the invite I had to find a room with twice the size. And we didn’t even invite mathematicians :)
