      Description

      At the moment, if
      a) a transform contains several uses of the same dataset
      b) that dataset is evaluated inline instead of as a child query

      then in some situations the dataset is evaluated more than once. Possibly including:

      • if the common part of the dataset doesn't create a temporary
      • if some of the uses are conditional
      • if assigned to some fields before being used.

      One example that seems to suffer from this is uk4.eclxml (private test suite) once the DATASET(count, transform) can be generated inline.
