in thread Closure on Closures

Right, that's a very clever use of closure. Maybe I didn't read enough, but I don't see such technique being used too often. It's good for avoiding more deliberate tempering with variables in a package. Isn't the usual lexical scope good enough to avoid accidental clashes between things?
