We're getting a little far from my real question, since caching the examples is IMHO a hack to cache the most expensive part of the computation, while the whole 'doc ought to be cachable, but....
I forgot what my own code was doing. That's basically what I'm doing: (define (make-cached-eval name . rest) (define ev (make-log-based-eval (cachefile name) (if (file-exists? (cachefile name)) 'replay 'record))) (for ([r rest]) (ev r)) ev) I'm using with-cache's `cachefile` just to generate and manage the file path, so it ends up in have a good place. I was trying to do something more complex earlier, but it didn't work.
