A fairly limited amount of chest-thumping, as I remember it.

Python advocates shouldn't sneer at other languages. There's no need. If
you like Python, use it because of its merits, not because it's better
than something else.

Having said which, I must say that Python's "breaking backward
incompatibility" is of a somewhat different nature than (say) Visual
Basic's. It was known about for *several years* in advance, even before
Guido went to work for Google and finally had time to get the work
underway. Also it's defined to be a singular event, not a continuous set
of creeping changes. Python 3's updated syntax now constrains the
developers in the same way that Python 2's used to.

I wouldn't say that could remotely be described as "constantly" breaking
backward compatibility.

That's the way some people operate, but by no means all. Is it the
language or the people that are pissing you off. You sound a little
discontented for a c.l.py reader.
