I am curious if there is any news on this issue. My understanding is that since this is a new feature, nothing will be committed until after 2.6 comes out, but it would be really nice if I could use annotations in 2.x.

[warning - mini rant] Reason is, I am using 3.0a for now for this project, but I am sorry to say that using parentheses for raising exceptions drives me up the wall, and I don't like using them for the former print statement either. I suspect this is partly due to the fact that I'm using 2.5 for work, so I don't have the option to mentally "switch over" to the Python 3 way. /rant Does anyone have an annotations patch floating around against the trunk / 2.6b, or failing that, does anyone have opinions on what my chances are / things to look out for if I fiddle around with the annotations patch from the py3k branch? (My understanding is that this is revision 53170).

I give this approximately 0% chance of happening. It's a really complex change to the syntax and code generator. Your motivation is also suspect: 2.6 is supposed to be a stepping stone towards 3.0, not a safe haven for people who don't like certain 3.0 features. Just get used to print(). Parentheses for exceptions has been allowed since approximately Python 2.0, so you have even less of an excuse there.
