> It's important to remember Rust's borrow checker was computationally infeasible 15 years ago. IIRC borrow checking usually doesn't consume that much compilation time for most crates - maybe a few percent or thereabouts. Monomorphization can be significantly more expensive and that's been much more widely used for much longer.
