   Beside this, I have a question: I saw in some cases the following warning:
   
   ```
   rule XXX contains an optional block with at least one alternative that can match an empty string
   ```
   
   Is this a big problem? Actually I think that we can't avoid this as some alternative indeed can match an empty string for example in case of `inmemoryTableClause`:
