[Twisted-Python] RFC: Dropping support for Python versions prior to 2.1

[Itamar Shtull-Trauring]

Hi,

We've been discussing dropping support in Twisted for versions of Python 
prior to 2.1. There will be a number of limitation for people developing 
Twisted itself, though not, of course for people *using* Twisted - the 
coding standard will probably disallow list comprehensions, print>>, and 
import X as Y.

On the plus side, 2.1 will allow use of new features such as weak 
references, string object methods and so on. Additionaly, pyOpenSSL does 
not run on Python 1.5.2. On the other hand, 2.1 is less commonly 
installed than 1.5.2.

So, do any of you (users and developers) mind if 1.5.2 is no longer 
supported? If so, this is the time to speak out and say so.
