In the current draft, read-directory already returns names one by one,

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

No, or at least I am not; I don't think the idea makes sense.

There 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
