A simple test follows:
Hello, world!
Now perform an iterator test:
Item 1 of 5: one
Item 2 of 5: two
Item 3 of 5: three
Item 4 of 5: four
Item 5 of 5: five
And again for equivalence:
Item 1 of 5: one
Item 2 of 5: two
Item 3 of 5: three
Item 4 of 5: four
Item 5 of 5: five
And finally with the old model:
Item 1 of 5: one
Item 2 of 5: two
Item 3 of 5: three
Item 4 of 5: four
Item 5 of 5: five
