Just thought somebody might find this interesting/useful.
I wanted to use the new 'for' syntax to loop through all the lines in a text file; something I find myself doing quite often.

A simple example:

It required making two classes: FileLineIterable, and FileLineIterator.
You might find this useful as an example for implementing your own iterator class.
