[Rd] Autocompletion for the new S3 generic @ method?
I agree, this is a good idea and would be very helpful in interactive contexts. I have a draft patch implementing this feature here: https://github.com/r-devel/r-svn/pull/122 (Append ?.patch? to the URL to get a raw patch.)

Hi Tomasz, I haven't had a chance to look at your patch yet (also I can't accept it as I'm not on R-core), but patches for consideration should be submitted to bugzilla (https://bugs.r-project.org), not the unofficial github mirror of the the SVN repo.

Thanks, we are discussing the details, but we will definitely add something along those lines before 4.3.0 is released.
