Java.net is currently running a poll on closures, to get a feel for the strength of support for each proposal. Obviously, this poll has no power, but it is useful to see at a high level what the communities opinion is.
Personally, I'm really pleased with the level of support FCM has had in the vote so far, on this blog and privately. Now I'd like to encourage you, if you so desire, to vote and support FCM. Thanks!
