This is related to my interest in a zero-length Range. I may have an Array with values 1-10 and want to process a request for values > 10. I have code that gets indices from a binary search and creates a Range that is used to "section" the Array. Currently, I'm using nulls to handle zero-length results, but it would be much nicer to have empty Ranges and Arrays that would do the right thing.
My applications are similar. I don't use empty arrays explicitly, but they are useful for handling limiting cases such as this without special code.
