It seems that Python 3 is more significant for what it removes than
what it adds.
That's certainly the focus of an explicitly backward-incompatible
upgrade, yes.
What are the additions that people find the most compelling?
Most of the additions that will go into 2.6 are doing so because
they'll appear in 3.0. That's a benefit: anything from 3.0 that makes
sense to add to 2.6 will go in; the rest of 3.0's changes are mostly
backwards-incompatible (i.e. removals and conflicting changes).
I find the following compelling:
- 'str' becomes Unicode type, 'int' becomes unified-int-and-long
type <URL:http://www.python.org/dev/peps/pep-3100/>
- Consistent, unambiguous integer literal syntax
<URL:http://www.python.org/dev/peps/pep-3127/and the 'bytes'
type for non-text strings
<URL:http://www.python.org/dev/peps/pep-3112/>
- Default source encoding is UTF-8
<URL:http://www.python.org/dev/peps/pep-3120/and support for
non-ASCII identifiers
<URL:http://www.python.org/dev/peps/pep-3131/>
- Reorganisation of the standard library for consistency
<URL:http://www.python.org/dev/peps/pep-3108/>
- Renaming raw_input to input, so 'input()' does the obvious thing
<URL:http://www.python.org/dev/peps/pep-3111/>
- Clarification of 'raise' and 'except' semantics
<URL:http://www.python.org/dev/peps/pep-3109/>,
<URL:http://www.python.org/dev/peps/pep-3110/>
- Abstract Base Classes
<URL:http://www.python.org/dev/peps/pep-3119/>
- everything that's being added to 2.6 :-)
