    Because neither

    <label>: (nor)
    case <expr>: (nor)
    default:

    are statements by themselves. They are an optional start of a statement. The
    ebnf looks like:

    statement:
    labeled-statement
    | expression-statem
    | compoundstatement
    | selection-statement
    | iteration-statement
    | jump-statement

    labeled-statement:
    identifier ':' statement
    | 'case' constant-expression ':' statement
    | 'default' ':' statement
