Hello Liliana!
I think that I have fixed all of your recommendations with the package definition.

I love the yasnippet function, would you (Guix in general) mind if I use
their yasnippet config as reference (It is in the Guix repository after all)

Also, if you don't mind answering a question of mine, in Magit the saved
Patch doesn't this section:

Is this a problem on my side or am I running the wrong command (in the
commit buffer running W+s)

And Like I said before, let me know if there's any way this package definition can
be further improved! (First time making a patch)

Thanks for your help,
Haider.
