how about -v<version> ?

there has been talks about compatibility "modes" (probably an option,
but probably also a way to set options programmatically), as a way to
help people prepare for "Python 3000".  I think we might expect some
of it in 1.7, and more of it in 1.8 (if that ever materializes).

but hopefully, Python 3000 will be completely free from modes.

guido tried to do the latter.  guess he didn't expect that everyone was
using connect in every single script they'd written ;-)

yeah, but at the moment, guido and the rest of the 1.6 team have
more important things to do than to deal with the spanish inquisition.
so I'm afraid it'll have to wait until that -v1.6 switch is in place.
