The second one is waaaay to indented. For myself I sometimes end up
wrapping the lines (although I don't love it) so it looks like this:
(gexp->derivation
"check-deb-pack"
(with-imported-modules '((guix build utils))
#~(begin
(use-modules (guix build utils)
(ice-9 match)
(ice-9 popen)
(ice-9 rdelim)
(ice-9 textual-ports)
(rnrs base))
