     * We generally don't need or want semicolons, but we should require them
     * before so-called continuation characters like "(" and "[", because
     * automatic semicolon insertion doesn't "fix" cases like this:
     *
     * ```js
     * const foo = 'bar'
     *
     * (() => {
     *   console.log(foo)
     * })()
     * ```
     *
     * Our rules only require semicolons in cases like this, where ASI doesn't
     * apply and it would be interpreted as:
     *
     * ```js
     * const foo = 'bar'(() => { console.log(foo) })()
     * ```
     *
     * ...yielding the difficult-to-decipher error:
     *
     * ```
     * Uncaught TypeError: "bar" is not a function
     * ```
