What is the purpose of keeping the field order?  

And when function call involved, what is the order of the parameters? Like {{select func(a, b, c) from t}}, should the order be {{a, b, c}} or {{c, b, a}}

> The current `ProjectionTranslator # identifyFieldReferences` method uses the` Set` temporary save field, causing the field to be out of order, although the out of order is also working, but I think the order is better than out of order. So I want to improve it,Orderly extraction field.
