             Summary: Initial the digest of RexRangeRef to avoid null string
                 Key: CALCITE-3599
                 URL: https://issues.apache.org/jira/browse/CALCITE-3599
             Project: Calcite
          Issue Type: Improvement
          Components: core

Currently, the digest of {{RexRangeRef}} is always {{null}} which is confusing 
when we try to debug the code. I suggest changing it to a more meaningful 
string such as {{offset(0)}}.
