I think I love the new standard already. I specially love user-defined literals. Too bad they'll leave out the the file system library. I was looking forward to it.
Well, first of all, concepts change everything. Second, the definition of rvalue references requires that std::pair, simple as it is, have no less than 18 different constructors. I wonder how mere mortal programmers will cope with them? Most likely they will ignore them since rvalue references are merely an optimization and do not provide any additional functionality to the language. Thirdly, the syntax for lambda expressions is hardly any better than what boost::lambda already provides, IMO.
In short, I don't see a lot in the new standard that makes me want to go out and upgrade my compiler today.
