> I've ran into bugs multiple times because I ignored an error result, or overwrote the "err" variable and swallowed an error. Errcheck helps a bit.

Any reasonable code review process would catch these (very obvious) problems.

my golang code is littered with err handling etc, it’s easy to miss something over the course of dozens of prs. This is something best caught at compile time or by a linter. Or tests which I am often lacking

I find code review unreliable at best for catching bugs or logic errors, but depends on the reviewer
