Hi, I was interested in writing a package specification for the haskell
language server, but when I attempt to import the package I encounter an
undecipherable stack trace:

--8<---------------cut here---------------start------------->8---
$ guix import hackage haskell-language-server
Backtrace:
In guix/import/cabal.scm:

ERROR: In procedure append:
In procedure append: Wrong type argument in position 1 (expecting empty list): #f
--8<---------------cut here---------------end--------------->8---

What can I do to debug this?  For context this is my current version and
I am using Guix on a foreign system via Debian:

--8<---------------cut here---------------start------------->8---

That’s probably because something is missing in the Cabal parser.
Well, I have not investigated but considering bug#38946 [1] which reads
something very similar,

--8<---------------cut here---------------start------------->8---
$ guix import hackage cabal-helper
Backtrace:
In guix/import/cabal.scm:
   875:28 19 (eval _)

   875:28 13 (eval _)
   875:28 12 (eval _)

   872:13  1 (eval _)
In unknown file:
           0 (append #f (("other-modules" ("CabalHelper.Compiletime.Cabal CabalHelper.Compiletime.CompPrograms CabalHelper.Compiletime.Compat.Envir…")) …))

Well, I somehow agree with Robert’s comment in [1], quoting:

        Note that there’s quite a few issues with the cabal parser, and
        the format is pretty baroque, to the extent that I wonder
        whether it wouldn’t be better to delegate the parsing to cabal
        itself.
