i feel like we are going in circles^^
take the ```IterableIterator``` class, rename it to ```Iterator```, add
into docu/javadocs "Iterator on which the for-each statement can be used. the
for-each loop starts at the element that next() would return".
traversable-once characteristic is obvious, supports for-each statement,
solves these odd exception issues andd the differences to a normal iterator can
be summed up in 2 lines. bonus: less API breaking, since its just an import
that has to be changed.
we cant use a name that makes all properties obvious (because
```IterableIterator``` is an odd name). the for-each statement not being
obviously usable is imo a lot more desirable than then user creating faulty
programs hitting exceptions based on false premises how the ```Iterable```works.
