Thanks!

I looked into the Guix source and reproduced what "guix package -m" does
to load a manifest file.  Make-user-module procedure appear to be used
in Guix to dynamically create modules for running user code.  I could
have simply used "load" here, but then all the files would be loaded in
the same environment and could potentially interfere with each other.
