----------------------------------

             Summary: Improve the performance of the new Parrot parser
                 Key: GROOVY-8910
                 URL: https://issues.apache.org/jira/browse/GROOVY-8910
             Project: Groovy
          Issue Type: Improvement
            Reporter: Daniel Sun
            Assignee: Daniel Sun
         Attachments: onload_from_slack.groovy

statementExpression rule is very inefficient, we should merge expression into commandExpression
to reduce looking ahead.

The attached file cost 5.7s on parsing before tuning but cost only 2.5s after tuning.
