Etoile is great project with many interesting concepts. I always wished that Apple would somehow get inspired by the LanguageKit. I guess that AppleScript was good enough...

I miss the talks of pre-Etoile days on #gnustep.

Project Etoile is awesome! It is also further along in the Obj-C/ST integration than ObjST.

What distinguishes ObjST is that it is taking the language further in terms of expressive power and adaptability, with Polymorphic Identifiers, (higher order) messaging mediated via first class references and dataflow connectors.
