Well, I don't entirely agree here; there are some valid concerns about Py3-specific design decisions. Take, for instance, conversion of `str` to Unicode. That

* significantly increases the memory footprint as every character requires 2-4 bytes to encode.

* does not provide 1-to-1 correspondence with certain Asian encodings.

* creates an impedance mismatch between Python and byte-oriented filesystem/internet protocols.

Personally, I believe total Unicodification in Py3 was worthwhile, but from some perspective, it could be seen as a regression.

That said, I'd love to hear what specifically in Py3 could cause such a burst of hate.
