- Add support for ad-hoc hardcoded typing rules - Add rules for int, double and num, for + and * I'd like your opinion on the general strategy before adding dozens of ad-hoc rules. So if you LGTM this CL, I'll add them in a later CL. Note: this is different from trusting the types from the signatures of, say, int's methods because we can overload some methods. Defaulting to trusting the types might be a good replacement for what currently returns Dynamic.
