Could you elaborate? If you are worried about Python 2.X scripts,
note from the PEP that the only things that will ever show up in
Python 2.X are:
PendingDeprecation warnings, which by default are not displayed,
and documentation notes directing users of getopt and optparse to
I think these messages are useful for folks using 2.X who some day
would like to migrate to 3.X, and at the same time should have zero
effect on existing scripts.
If you think getopt and optparse should stick around in 3.X, why is
that? If you think there are things that getopt and optparse do better
than argparse, could you please give some examples?
Where did you get that preposterous hypothesis?
Did Steve tell you that?
