Go's approach to generics is decent. It gets some of the benefits with some of the downsides. When coding in Rust, I am always so desperate for better compile times, especially for "clean" compilation because I make heavy use of Nix for various things and that comes into play a lot. (I don't run all of my builds in Nix, but I use Nix for virtual machine based integration testing for example, and that would involve doing a clean Nix build of the program.) So I guess while I get why some people were disappointed when Go didn't choose full monomorphization I appreciate their commitment to keeping fast compile times a priority. And it is certainly a hell of a lot nicer to be able to do proper generics at the language level on maps and slices in any case.
