I'm not sure exactly what's going on, but I assume it has something to do with the call stack and creating objects in the global scope. Note, the effect occurs only when dictionary iteration/item access results in object creation in the global scope. So, this will trigger the effect: myvalues = mydict.values() but this will not: mydict.myvalues() # No assignment here.
