This refers to second and third milestones of Elixir's type system. It is a continuation of #13227 and can only be started once that is completed.

New constructs and APIs will be added to Elixir:

  • Define a construct for typed structs (field documentation, parametric definitions, private fields, deprecate empty structs)
  • Define a construct for type aliases
  • Define a construct for type signatures
  • Define a construct for typed behaviours
  • Define a construct for typed protocols and implementations (parametric protocols)
  • Define a construct for Erlang FFI

At the descr-level, we need to support:

  • Occurrence typing
  • Recursive types
  • Parametric polymorphism and anonymous function call inlining
  • Strong arrows
  • Row polymorphism
  • Behaviours
