Replacing the bash binary with the elixir binary, a common bash cell can be used as elixir interpreter:

IO.puts "hello elixir"

Replacing a python next-repl interpreter with an elixir repl, which loads the repl code from a (transcluded) cell, we can upgrade an elixir interpreter to a next repl, opening a port on 9999 and reading code from it and responding with transit events.

python_path="$(which python)"
echo "#!/usr/bin/env bash" > "$python_path"
echo "$(which elixir) -e \"\$(cat <<EOS 
$(cat <<EOM

)
)\"" >> "$python_path"

This is the basic nextrepl code:

{:ok, socket} = :gen_tcp.listen(_port = 9999, [:binary, active: false, reuseaddr: true, ip: {0,0,0,0}])
{:ok, client} = :gen_tcp.accept(socket)
tag_write = fn(tag, data) ->
  line = "[\"~:#{tag}\",{}]"
  :gen_tcp.send(client, line)
end
tag_write.('nextrepl/hello', {})
tag_write.('prompt', {})
loop = fn(loop) ->
  {:ok, data} = :gen_tcp.recv(client, 0)
  IO.puts "received "
  IO.puts inspect(data)
  
  loop.(loop)
end
loop.(loop)

This would be a stateful elixir repl. It does not finish booting yet,

because the eval step is missing, but that would be only some few more lines...
