Anyone want to try to explain what he's on about with the first example?

    bar, err := foo()
    if err != nil {
      return err
    }
    if err := foo2(); err != nil {
      return err
    }

The above (which declares a new value of err scoped to the second if statement) should compile right? What is it that he's complaining about?

EDIT: OK, I think I understand; there's no easy way to have `bar` be function-scoped and `err` be if-scoped.

I mean, I'm with him on the interfaces. But the "append" thing just seems like ranting to me. In his example, `a` is a local variable; why would assigning a local variable be expected to change the value in the caller? Would you expect the following to work?

    int func(a *MyStruct) {
      a = &MyStruct{...}
    }

If not why would you expect `a = apppend(a, ...)` to work?

That might be it, but I wondered about that one, as well as the append complaint. It seems like the author disagree with scoping rules, but they aren't really any different than a lot of other languages.

If someone really doesn't like the reuse of err, there's no reason why they couldn't create separate variable, e.g. err_foo and err_foo2. There's not no reason to not reuse err.
