In the current draft, read-directory already returns names one by one,
then (eof-object) at the end. That matches the SRFI 158 definition of a
generator unless I misunderstood something.
SRFI 158 generators can't take arguments, so you need a little let-over-lambda wrapper to provide the directory-object argument. See the code I just posted.
Are you talking about the
generator-that-returns-sublists-of-the-full-list that we discussed much
earlier?
No, or at least I am not; I don't think the idea makes sense.

http://vrici.lojban.org/~cowan xxxxxx@ccil.orgThere are books that are at once excellent and boring. Those that at
once leap to the mind are Thoreau's Walden, Emerson's Essays, George
Eliot's Adam Bede, and Landor's Dialogues. --Somerset Maugham
