Thanks for analyzing this, Matthew. I ended up going with the "letrec"
approach.
(I'm generally interested in I/O performance, and am fond of "sync" and
its variants. My immediate need was to make the "charterm" object in my
character terminal library a synchronizable event, so that my new
Rackonsole library could do a "sync" on both the terminal and on the log
receiver. I'm happy to report that Racket's very rich events system
worked great.)
