Yeah, this is a good idea. You can kinda already do it, see my post here: S4TF in colab (error) - #6 by marcrasi
It would be nice if the commit hash and version string were exposed as variables in Swift itself so that you can query them from a running swift notebook. I don’t know if they are. Finding and/or exposing them might be a good starter task for someone interested in hacking the Swift compiler/stdlib!
