I am all for that. Not that many tests fail (in the order of 1%), but it is a
pain to disable them by hand. That is why I have not done an update in a while
- I am running a more recent version on my GUIX_PACKAGE_PATH with tests
disabled.

The simple way is to remove a number of test files. The majority of
tests will work and since Erlang's tests also work - there are a large
number of them (thousands). I would be fully confident the new package is fine.

That would be really cool. I would like support for Elixir packages. I
run a REST service and GraphQL is coming. I don't like to depend on Elixir's
packaging system, though it has been reasonably OK so far. It will break at
some point - as they all do. Elixir's packaging is similar to D's dub, so we can
take some cues from that. Elixir packages everything in the local source tree -
similar to Ruby's bundler.

Must be a dependency that changed. Hmmm. August 2nd.

Must be it ;). It is great people are updating Erlang! These are great
programming languages.

I am happy to work on Elixir with you.
