> Python only just barely survived the jump from 2 to 3.

I really don't think this is true at all.

Python 2 to 3 took a really long time, it was a real struggle, lots of people stayed on 2 for a really long time.

But I really don't think Python was close to dying the same way Perl has/is. There was no risk of Python not "surviving" in my opinion.

There was always a clear way forward and people were actually moving. The mass migration of millions or billions of lines of code from 2 to 3 actually happened and has many high profile million+ line migrations, like Yelp or Dropbox.

There was never anything similar for Perl 5 to 6, totally different situation.
