// user to invoke. For example, say there is:
//
// new JObject { { $$ } }
//
// Technically, the user could be calling the `.Add(object)` overload in this case.
// However, normally in that case, they would just supply the value directly like so:
//
// new JObject { new JProperty(...), new JProperty(...) }
//
// So, it's a strong signal when they're inside another `{ $$ }` that they want to call
// the .Add methods that take multiple args, like so:
//
// new JObject { { propName, propValue }, { propName, propValue } }
//
// So, we include all the .Add methods, but we prefer selecting the first that has
// at least two parameters.
