Description Ed Willink CLA 2011-06-25 02:49:52 EDT 
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?
