Comment (by schlessera):

 I'm interested in tackling this for 4.9.

 I'd like to investigate using proper PHP iterator objects, and provide
 some custom magic so that they can transparently cache into
 transients/object cache.

 The main benefit is that you don't pull in all files and folders into
 memory just to pass them around, but rather you prepare an iterator object
 and pass that on. In some cases, the actual iteration will never happen as
 it is not needed, and in some cases you'll only end up with a partial
 iteration, which saves IO and memory as well.

 Once the iterators are built, they can easily be adapted to replace the
 above functions.

 Is there anything that would speak against such an approach?
