HI everyone,

I did some work on your review and have a couple questions before I submit
the next patchset.

* My questions for Martin:

> I'm trying to convince everyone to leave in the crago-inputs

I like this idea. I think I will do it if you don't mind. It's either that
or add hidden? #t to the properties, right?
Whether to add #skip-build? #t to the packages is the last piece of review
I need to fixup.

* Discussion for Nicolo:

> - rust-demo-hack@0.0.5: all the source URIs are unreachable

I guix build rust-demo-hack@0.0 and got the download. Maybe it was a
temporary network issue or something?

> Also:
> - rust-miniz-oxide-c-api-0.2: defined but not used

It is used by at least rust-flate2 I think.

* Work I did based on Nicolo's suggestions:

** Fixed

Ah, that's because I left off my first package from the patchset. It will
be included next round.

Thanks, looking forward to having ripgrep upstream :)
