What I had in mind when talking about that standard library thing was one case in particular that I had found where someone had to implement deduplication of elements in a vector/array/list (or whatever Go called it, don’t remember that bit) locally because Go does not support function generic over the type of container element.
And the whole if err != nil { return err } bit is a huge part of what makes Go code unreadable. I have also found at least half a dozen bugs related to that construct where people just did not print any of the relevant information in error cases because of the lazy copy&paste of that construct in cases I had to debug.
