Neat example!  But what is make-user-module doing, and is it necessary?

I checked in the Guix source and found that this procedure uses the
procedure make-fresh-user-module, which comes from the (ice-9 boot)
module and is not documented in the Guile Reference manual.  I stopped
investigating when I checked the ice-9 source code and found that it did
not contain an immediately helpful docstring or comment.  It feels like
maybe make-fresh-user-module ought to be documented in "(guile) Module
System Reflection", but it isn't.  Unfortunately, I don't have time
right now to dig deeper.
