 A check against an array of //Object// leads to two cases: A check against an array of //Object// leads to two cases:
   - The reference points to an array of regular classes: the check returns ''true'' if the dimension (of the type to check against) is lower or equal than the actual dimension.   - The reference points to an array of regular classes: the check returns ''true'' if the dimension (of the type to check against) is lower or equal than the actual dimension.
