In the current draft, there's a "read-directory" procedure which does
this really nicely. It easily supports generator-style and fold-style
helper procedures, as well as directory ports (i.e. open-directory
returns a special kind of port as in Gambit). I'm really happy that
something so simple and adaptable was found.
