Elixir

In a third-party project, in the models, I've encountered functions like this:

  def changeset(model \\ %__MODULE__{}, params) do
    model
    |> cast(params, @required_fields ++ @optional_fields)
    |> validate_required(@required_fields)
  end

How can a function have a default argument which is both a) first and b) followed by a mandatory one?

What's interesting, they work properly.

Does anyone else think that Elixir could be really well-suited to writing fediverse applications? I'm really tempted to try my hand at writing an alternative Lemmy backend. If anyone is feeling the same way, I'd be more than happy to host a project on my GitHub and give y'all access and we can see what we can do.

A post on mutability and state in Elixir. Functional yes. Immutable? Eeh..

We couldn't get Dialyzer to work well until I found this, hope it's helpful for others!
