The compiler team's explanation

A break statement without a label appeared inside a labeled block.

Erroneous code example:

loop {
    'a: {
        break;
    }
}

Make sure to always label the break:

'l: loop {
    'a: {
        break 'l;
    }
}

Or if you want to break the labeled block:

loop {
    'a: {
        break 'a;
    }
    break;
}
