Wow, thanks!  I think pflask is exactly what I'm looking for.  I'll
write a guix package and do some experiments with it soon.

It seems that with pflask, there's no need to add anything to dmd.  We
could extend guix system to use it to generate containers.

This is a really great starting point.  Thank you very much for
pointing me in the right direction.
