(Previously it waseven worse than that, which is why deprecation warnings are no longerdisplayed by default).For things that we have no intention of deprecating in 3.x, but willlikely ditch in a hypothetical future Python 4000, we'll almostcertainly do exactly what we did with Pyk: later in the 3.x series,add a "-4" command line switch and a sys.py4kwarning flag to triggerconditional deprecation warnings.So, assuming things continue as they have for the first couple ofdecades of Python's existence, we can probably start worrying about itsome time around 2020 :)Cheers,Nick.-- Nick Coghlan | ncoghlan at gmail.com | Brisbane, Australia
