This is a good example of "stringly typed" software. Golang designers did not want exceptions (still have them with panic/recover), but untyped errors are evil. On the other hand, how would one process typed errors without pattern matching? Because "catch" in most languages is a [rudimentary] pattern matching.

Go has typed errors, it just didn't use it in this case.

The consumer didn't, but the error in the example is typed, it's called `MaxBytesError`.

Only since go 1.19. It was a stringy error since go 1.0 until then.
