Subject: [PATCH] add missing pass to playground
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It's pretty tedious to keep the playground in sync w `Pipeline` — we need some
abstraction so we can write the sequence of passes once and reuse it (while
inspecting intermediate states).
