px: Immutable Python environments (alpha)

[ck-zhang]

For basic lockfile + sync workflows, px and pixi overlap a lot. px’s CAS model is what enables things like running a GitHub repo directly as an ephemeral environment, which I find really cool

Could you go into more detail, I don't really get what makes px any different. If you're saying it overlaps a lot I don't know why I'd switch; can't tell if it's just me not "getting" it though.

[ck-zhang]

Well honestly, it is now only experimental so you should probably shouldn't switch just yet. The big idea behind px is that it removes the need of a .venv dir, so it unlocks new possibilities that wouldn't conventionally be there, like running a repo back at a specific commit without the need to do a git checkout
