The problem is that ‘package-with-guile-2.0’ needs to resolve
‘guile-2.0’.  So if you use it at the top-level, then (gnu packages
guile) has to be fully loaded, or you have to be in (gnu packages guile)
itself and ‘guile-2.0’ has been defined above.

I think we can get around it using this cute hack.  I’ll commit it if
that’s fine with you.
