Really? I miss Brazil and version sets regularly and often think about reimplementing the parts I find valuable on top of an existing package system.

Having self contained workspaces with all dependencies in any language, fine grained ability to replace any package with a local build, and the simplicity of package config (for most languages) was awesome.

Having to use _n_ language dependent build systems without interface pinning or reproducible builds since leaving sucked, imho. Checking out a package and running `bb` to get an artifact was just so satisfying.
