Julian Hyde commented on CALCITE-2556:
--------------------------------------
{quote}{{ReduceExpressionsRule}} uses {{RexSimplify}}.
That is basically the same code.{quote}
Not true. While it is true that {{ReduceExpressionsRule}} uses {{RexSimplify}},
it goes further. It is able to reduce 3 + 4 to 7, and {{RexSimplify}} is not
capable of that.
> RexSimplify: not(trueLiteral) could be simplified to false
