While we're talking about changes for 1.0, how do people feel about
dropping Python 2.6 support. I think we decided that we need to keep
Python 3.2 support for the time being because of Debian, but what
about 2.6? According to
https://www.python.org/download/releases/2.6.7/, the Python 2.6 series
hasn't been supported for security releases for over a year. But what
matters is if people are using it. If there's a good case to keep it
for the time being, we can.
Some advantages of dropping support is that there is a lot of nice
syntax backported from Python 3 in Python 2.7 which is unavailable in
Python 2.6. Some useful things in Python 2.7:
- Set literals (like {1, 2, 3} instead of set([1, 2, 3]))
- Set and dictionary comprehensions(like {a for a in stuff} or {a: b
for a, b in stuff})
- OrderedDict in the standard library
- Multiple context managers in a single with statement (I don't know
if we ever do this, but we have a lot of experimental context managers
like assuming() and evaluate() and this makes it easier to combine
them).
- argparse (we can use it instead of optparse in our scripts like isympy)
- collections.Counter (could be useful, it's effectively a multiset)
But again, the main question is if people are using it.
