- Replace guarded constructors with guarded types, introduced only by
  guarded expression abstraction, and with a new explicit application form
- Kind polymorphism
- Generalize type classes to constructor classes
- Initial compilation of client-side code to JavaScript
- Initial support for mixed client- and server-side programming (i.e., "AJAX")
- src/coq: Coq formalization of a core Ur-like calculus
