@bryanhonof sorry I didn't see your post! I played a lot with it throughout the rest of the day but eventually gave up. I talked about it on the NixOS Matrix room (I'm
@mat:allpurposem.at there) and it seems it's just not yet supported in nixpkgs. I did find a repo by the same person that made the nixpkgs PR that *would* allow `import std;` to work, but I had issues using it. You can see my open issue here:
