The current model I am using assumes that selecting-read is passed a
list of objects, and each object can have sub-objects (children).

Every object has it's representation calculated and is displayed in the
popup buffer. Any objects can be selected, even those with children.

Most GUI menu interfaces I am familiar with do not allow selecting a
menu that has children, but only "leaf nodes". If selecting-read should
both have a buffer interface as well as a GUI interface, the abstraction
should be restricted so that it fits both paradigms.
