This is a feature. The statement might not succeed. You shouldn't use it as part of a bigger expression and assume it will work.

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

this makes it totally clear that foo can fail, and if it does, then we won't call bar.

In languages with exceptions, this line just looks like

    bar(foo())

And then you can't tell that foo might fail and we might not call bar. Even if you wrap the whole thing in a try/catch, it's not clear.

This is why exceptions are an anti-pattern. They hide what functions can fail and what happens when they do.
