Hey Julien,

Sorry for the delay. I got your patches the day you sent them, but have
been rather busy and have inadvertently put them off and forget they
existed. Woops! My apologies.

I have Cc'ed Amin Bandali as we are both co-proposers for the formal
methods working group. These type checking and safety systems are
obviously very important to the formal methods community and software
developers unaware of the nice guarantees offered by them. So i'd like
to see this get added and in shape regardless of if the Guix maintainers
"approve" our working group proposal.

Thank you for sharing this. I will take another look at it soon and let
you know what I find. :)
