Hi Leo,

Giving a look to the bug tracker for the next release, I see this
bug. :-)

The doc/ does not apply anymore.


Instead of these ’eqv?’

I propose ’match’ which is more coherent with the Guix style.  Well,

Patch attached.  Well, it could be nice to add a test in
tests/guix-lint.sh for that.  WDYT?
