We used all that extra time for *formal proofs* that Tree Borrows indeed allows at least some of the optimizations that we hope to gain from it,
and to carry out an extensive evaluation of Tree Borrows on the 30 000 most-downloaded crates on crates.io.
This overall package of implementation, proof, and evaluation impressed the PLDI program committee enough that we got a *distinguished paper award*. :-)
