The type assertion x.(SomeInterface), when x already has type SomeInterface, can only fail if x is nil.

Usually, this is left-over code from when x had a different type, and you can safely delete the type assertion. If you want to check that x is not nil, consider being explicit and using an actual if x != nil comparison instead of relying on the type assertion panicking.

Bad practice

func foo(x i1) {
    _ = x.(i1) // will panic if x is nil
}

Recommended

func foo(x i1) {
    if x != nil {
        // ...
    }
}
