[W503] False positive when assigning DB field to another DB field

Assigning a DB field to another DB field of the same dataset does lead to a false positive W503

DataSet.FieldByName('FIELD1').Text := DataSet.FieldByName('FIELD2').Text;

This might also apply to assigning an array property of an instance to another index of the same property and instance, but I haven't checked this, but this is something common. (e.g. list swap, exchange)
