I wonder what portion of all go code written is

if err != nil { return err }

It’s gotta be at least 20%

Can anybody explain the rationale behind this?
Exceptions don’t exists and ask errors must be handled at every level. It’s infuriating.
I actually kind of like the error handling. Code should explain why something was a problem, not just where it was a problem. You get a huge string of “couldn’t foobar the baz: target baz was not greebleable: no greeble provider named fizzbuzz”, and while the strings are long as hell they are much better explanations for a problem than a stack trace is.
