@arianvp @filippo i think NAR is more stupid than dirhash

@filippo yep, it's fairly understandable why dirhash was chosen; unfortunately, Go (among application ecosystems) is quite unique in having solved this problem. Someday, Nix will support extensible fixed-output primitives so that dirhash can be explained to Nix and then Go modules can be natively downloaded by Nix and fed to the rest of the Go packaging machinery.

@filippo Well, the Nix ecosystem definitely had appetite for that but the usage of dirhash made that quite hard because AFAIK it's not easy to go from dirhash to some raw SHA-256 or similar.

@filippo so I feel like you almost never need to look at go.sum except if you do use a system that allows only fixed output fetches and then go.sum is useful to predict more or less that hash, right?

@filippo but there's no hashes in gomod, is there?
