Pushed my changes here for anybody interested in taking a look
https://gitlab.com/swedebugia/guix/commits/npm2

(All my work build on the previous work of Jelle and Julien. Big thanks

Resume of its status: 
* recursive import works now.
* cyclic dependencies are not detected by the importer
* you have to import an earlier version by hand if a cycle is
encountered.

I imported 400+ packages in one day and most of them work out of the box
:)
