(A discussion on the TYPES forum).
Though no one answers the original queston this discussion is a very interesting discussion on the notion of type safety in programming language theory. Safe vs. unsafe; soft typing; static vs. dynmaic etc.
Toward the middle the concept of data abstraction comes to center stage, and some messages discuss objects vs. closures etc.
