For Sequence{Sequence{'this and', 'that'}, 'the other'}->collectNested(s : String | s.toUpperCase()) the iteration fails on a non-String first term. NB. The current IteratorsTest tests have no nested collections on which to collectNested is exercised. The nested test on collect is wierd Sequence{Sequence{'this and', 'that'}, Sequence{'the other'}}->collect(s : Sequence(String) | s.toUpperCase()) using a collection iterator for the double depth and then flattenning. Equivalent code is Sequence{Sequence{'this and', 'that'}, Sequence{'the other'}}->collect(s : Sequence(String) | s->collect(toUpperCase())) Philosophical issue. How can a Collection of collections be collected if collect iterates over non-collection elements?
