Adding TypedStruct to Core Elixir

[ericridgeway]

Has anyone ever discussed adding this to Elixir by default?

This library is just such an incredible improvement over the current Elixir version of having to duplicate every field name 3 times

defmodule Person do
  @enforce_keys [
    :name,
    :happy?,
    :phone
  ]

  defstruct\
    name: nil,
    age: nil,
    happy?: true,
    phone: nil

  @type t() :: %__MODULE__{
    name: String.t(),
    age: non_neg_integer() | nil,
    happy?: boolean(),
    phone: String.t() | nil
  }
end

# vs

defmodule Person do
  use TypedStruct

  typedstruct, enforce: true do
    field :name, String.t()
    field :age, non_neg_integer(), enforce: false
    field :happy?, boolean(), default: true
    field :phone, String.t()
  end
end

Not only does the current "idiomatic" Elixir way leave all the usual un-DRY problems of harder-to-maintain and easier-to-create-bugs... it's also MUCH less readable for newcomers trying to determine at a glance all the possible fields, which are required, what defaults exist, etc.

I love Elixir but TypedStruct's fantastic improvements solve such a large problem in the core library. Is there any way to suggest to the devs that this become the new idiomatic solution?
