Sure, but then you still need to wait until those features are widespread enough for companies to allow their use.
For example, last time I searched for it, most embedded and real time OS compilers were mostly C++11 compliant.
Interesting. Two years ago, Texas Instruments was still (barely) C++98 compliant. Glad to hear the world has progressed since then.
Nah, TI was still C++98 when I was searching for it.
The idea now is to standardize features that have already been implemented and well tested. This is one of the reasons why they want to delay adoption of concepts. When it is finally approved, all major compilers will have support.
