You're an idiot - you've wasted a decade

Default argument which is the 1st one and not the only one. How? (lemmy.world)
 

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.

Europe and US like to accuse others of everything. But they, strangely, don't like to be accused themselves in anything
