This means something like scheme/enter: scan the filesystem and reload any modules that have changed since the last time the code was run. Is there any downside to just using scheme/enter? Scanning the code, it seems the use of [compile-enforce-module-constants #f] will slow things down. I can't see any other downside, and it should be possible to get around this by loading the code into a new namespace each time. </blockquote><div> IIRC, scheme/enter works at the top-level and "enters" into the namespace of the module you are loading. My guess is that you are looking for something similar to what I asked about in the following thread: <a href="http://list.cs.brown.edu/pipermail/plt-scheme/2008-October/028094.html">http://list.cs.brown.edu/pipermail/plt-scheme/2008-October/028094.html</a> I implemented a mechanism call dyn-require that mimics dynamic-require, which checks whether the module had changed and reload if necessary. The basic idea is to replace (dynamic-require <module> 'symbol) to (dyn-require <module> 'symbol) This doesn't handle dependency reloading (I thought about it but it seems to open a can of worms so I didn't go down that route) and can share dependencies as well (to ensure the depended structs are the same ones). If this sounds like what you are looking for - let me know and I'll send you the code. Thanks, yc </div></div>
