The bulk of this rule is closely based on the logic from the original ESLint rule. One major difference between this implementation and the original though is the lack of a tokenizer. ESLint uses a proper tokenizer to find identifers, parentheses, brackets, and other tokens. For this rule, I opted to just manually search for the characters we might expect to find. I'm not sure how this will hold up in the real world, I expect it could lead to some missing cases potentially, but it at least works for all of the given test cases.
