Hi everybody, I have a question, more of an idea: should closures (or Smalltalk blocks) be included in the meta-model? You could see closure as a anonymous function, but with some special properties. They are becoming a very used feature in programming languages: Smalltalk, Lisp, Scheme, Python, Ruby, Javascript and others have closures and even the next versions of both Java and C# it's announced to have closures. Any opinions? Adrian Dozsa
