I'm looking at this to help with adding support for looking up package
replacements to store in the Guix Data Service.

Could you add a docstring and ideally a test?  (There might be
complications for the test, let’s see how it goes.)

Thanks!

I've sent an update patch now.

Maybe the test should search out for a package without a replacement, as
well as a package with a replacement, so that it tests both cases, but I
just went with a simpler approach for now.

Problem is that this test assumes sqlite has a replacement.  Maybe
precede it:

  (unless (package-replacement sqlite)
    (test-skip 1))

and remove (or (package-replacement …) …) and similar.

That way we’ll notice when the test is skipped.

Otherwise LGTM, thanks!

Ludo’.
