If you've Py_DECREFed it and then peek into its internals, you're aiming a gun at your foot. In theory, the decref could have been followed by some other operation (or a context switch) that allocated another object and happened to use the same address (not as unlikely as you might think, given that some object types use free lists). Always have a reference to something before you mess with it. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
