>With Go's multiple return values to represent errors, they are also known to be too easy to "forget" to even look at the error value.

How? Unassigned

    foo := myFunc()    # [...] assignment mismatch: 1 variable but myFunc returns 2 values

Assigned, but not used

    foo, bar := myFunc()
    fmt.Println(foo)    # [...] declared and not used: bar

Intentionally ignored

    foo, _ := myFunc()

Ignoring is a deliberate decision and trivial to review, lint and grep for.

Except for, I suppose, shadowing a variable before checking it

    foo, bar := myFunc()
    _, bar = myFunc()
    fmt.Println(foo, bar)

Which is more of a general grievance of quite some people, but I don't think that has much to do with multiple returns - and you definitely have to look at the error to pave over it afterwards.
