Documentation enhancement for methods of an iter-instance?

[ozett]

as a noobie i rely on the documentation to understand and use berry language.
the port for the iter-methods (on list-elements). is a little short.

could you add wich methods are available and how to use them on iter-instances?

i found some snippets about that here with the for-loop, but would be nice to have it in the wiki.

Therefore, if the return value of the iter method is an instance (instance) type, 
this instance must have a next method and a hasnext method.

what do you think?

I think that the doc is wrong, probably some old implementation.

Actually an iterator is just a function that returns the next value each time you call it and raises a "stop_iteration" exception when there are no more values. You can consider an iterator as a generator function, which is generally implemented as a closure to capture state.
