[lenish]

I concede that there are probably scenarios where this design makes sense within that context. I typically find that either I care about a single error and terminating the computation, or I don't care about errors at all. In the former case, the primitives in the sync package (or just an error channel which we send to once and close) are adequate. The latter case presents no issues, of course.

At $work we definitely have examples where we care about preserving errors, and if that tool were implemented in Go a solution like a Result struct containing an error instance and a data type instance could make sense.
