You should still be able to (trace) your functions and Araneida's  =

(e.g., handle-request-response). You could also wrap h-r-r, or modify  =

your methods, to preserve or print the request object, which will  =

I've done it =97 just play around with your methods and functions while  =

serving pages. If you have appropriate conditionals (e.g., you only  =

generate the in-development page for your username) you can even do  =

this while serving pages to users. Risky, sure, but it works.
