Julian Hyde commented on CALCITE-3260:
--------------------------------------
-1 The existing code is concise enough. With the new method, people will forget
to pass in an evaluator.
> Add support of evaluate method with default Evaluator.

> Currently, the public method *evaluate* of AbstractNode need a Evaluator
> object as parameter, but Evaluator class has default access control. This
> limit the access of *evaluate* method. So may be we can add an overload
> *evaluate* method with default Evaluator, thus, allow to evaluate Expression
> directly.
