I think the translation should happen before HIR, no? I mean, unless cleanly translates into not if, which then translates into jumps in the HIR, no? I admittedly know only general compiler techniques, not rustic.
I concur about the nice write-up though 😃

HIR doesn't contain jumps. MIR contains them. HIR is very similar to the AST, and is directly generated from (then converted to type-checked HIR during typeck). HIR desugars features like async/await (to generators), for and while let loops (to loop with breaks), if let to match, and more.
