* An iterator that iterates through a constant list of keys. This is
* handy if you know the list of keys is relatively short and you don't
* want to write your own iterator, and/or you know your own object state
* might change during iteration, so you would have to pre-generate the list
* of keys anyway.
*
* The creator of the iter is responsible for filling the 'keys' and 'values'
* lists by calling add(). If the 'values' list runs out of values before
* 'keys', the remaining values will be retrieved from the given generator
* (using get()) instead.
