The truth is, it's Python. I'm not looking for a great language, I'm looking for language that'll help me get work done... quickly and not give me a migraine if I have to come back to it (Perl). The 3 changes are just big enough to catch me (and every other Python programmer I've worked with) so that I can't just program, which tends to push me towards keeping it in 2.7 or switching to another language, where the similarities don't exist to pull me into bad habits. The whole mess really sours me on the language that made me love programming again.
