Majority of people dont care about new shiny, they care about things that broke or changed. Probably 90% of them started complaining because print statement is a function :).<p>Python 3 insistence on unicode hurts my brain. I had a &#x27;pleasure&#x27; of writing Python 3 script manipulating data produced by Python 2 (custom pickle). Ended up reimplementing whole Python 2 pickle library by hand, because apparently no one imagined a use case involving reading raw bytes into a buffer.
