Oh wait... it seems like the patch is not actually attached?  I assume
that must be an error!

Actually if I look at the raw view of the email I see:

--=-=-=
Content-Type: message/external-body;
 name="/home/samplet/code/guix-wip-racket/0001-gnu-racket-Ignore-bytecode-checksums-in-the-store.patch";
 access-type=local-file

Content-Type: text/x-patch
Content-ID: <87pnynbfy0.fsf <at> ngyro.com>
Content-Transfer-Encoding: binary



--=-=-=

So it looks like it should be attached, but I don't see the file
contents?

Perhaps this is an error on my end!  But I'm very eager to test this
patch!
