That's not new -- usually when you run the code you get a clean
environment with the old instantiation gone, but some core files are
shared across runs, so it's like trying to redefine things that are
already defined. Many files in racket/* will do the same. To debug
this kind of stuff it can be helpful to work on a copy of the file
that you want to edit, and rename it back over the original (and
recompile) when it's working.
