What is the status or portage 2.2?
It takes so long to get out of alpha. Has anyone here had any serious
problems with it? I've been using it for a a few years without any
accidents. Just wondering if I should be prepared for the worst.
I also remember reading in Changelog that 2.2 remains masked until 2.1 gets
enough testing, that was ages ago.

It initially suported set arithmetic (you could writes expressions like
"@set1+@set2/@set3"), I wonder why it was dropped :)
