Nice try. But thread-local storage requires threads, which are out of
scope for R6RS.
Can you give an example of the kind of dynamic binding you mean?
When I'm stuck in something boring John Cowan
where reading would be impossible or (who loves Asimov too)
rude, I often set up math problems for cowan at ccil.org
myself and solve them as a way to pass http://www.ccil.org/~cowan
the time. --John Jenkins
