Since these are not in C++11, we'll have to wait 10 years...
And there are lots of people interested in other sets of major features.
So who knows if C++17 will include it, and even it does, how long one can use it in production.
Until 2017 many native developers might just had moved into Rust, D, Go or whatever comes along.
Just look how computing used to be 5 years ago.
Bjarne believes that for C++17, we only have resource for 1 major feature, 2 medium features, and a dozen minor features.
