hi [mention:30bb505c1ca4449ca754b36b7a8ed1d7:e9ed411860ed4f2ba0265705b8793d05]  There is one important difference. index() returns a copy of the data.  square-bracket-notation returns a reference to the original data. it is crucial for using more complex data structures in saveInto where index() might not work.
