I don't know the how Scheme-48's interactive environment works, but I
don't see any inherent problem doing that with the model I suggest. 
Perhaps you can elaborate.

Sorry, I missed that.  I'm not happy to lift that restriction with your
model, unless the script header identifies the name of the module.  I
wouldn't want the script loader to have to scan for the library name or
try to figure it out by some implicit means.
