[plt-scheme] Incremental development with DrScheme or MzScheme

Please share your hack with the list.  While I agree that the DrScheme
workflow (especially with SchemeUnit) is usually better, sometimes I
write code that starts by defining objects which load and process lots
of data, and it can require odd work-arounds (serializing and
de-serializing the objects in question) when the REPL gets reset on
every code change.  And working through emacs, (require
"my-module.ss") doesn't reload the module....
