Description:collect clause is available from ballerina 2201.7.0[1].
Currently, the Data Mapper suggests to map with a query expressions only when both the source type and the target type are arrays. However with the collect clause, the query expressions can return a single value. Hence there is a possibility of suggesting to map with query expressions for array-to-int like cases too.
This issue is to track providing this support within the Data Mapper.
