The function that does it is eight lines of hand-written splitting. It&rsquo;s fast, and it has a bug everyone has learned to live with: <code>%20</code> and <code>+</code> come through undecoded.</p> <p>So someone opens a pull request that fixes it the proper way, with the standard library. Two lines replace eight. The review is easy to approve. This is a worked example we set up to show what jvq does with a change like that: a small repository with a pytest-benchmark suite, four real commits, and jvq 0.5.0 run on each one on a two-core cloud VM.</p>
