> Referencing variables in FOR loops with the cursor variable name doesn't work
> if the variable name is not lower-cased. Example:
>
> {code:java}
> FOR LoopCursor AS (SELECT * FROM VALUES (1), (2), (3) AS tbl(RowValue)) DO
> SET sum = sum + LoopCursor.RowValue;
> END FOR; {code}
> This would throw an "LoopCursor.RowValue cannot be resolved" error.
