The Concepts TS is a formally published ISO Technical Specification, and receives serious augmentation through the Ranges library TS. Lots of people want to see them be used, they're not a feature that's in the International Standard, so there may be some caution. We'll have a chat about how concepts and ranges can make your (students') lives easier, and why you should start teaching (using) them immediately.
Please bring a laptop, as there will be a demo that you might like to play around with on your machine. You will also need gcc 6.2 and this GitHub repository: https://github.com/CaseyCarter/cmcstl2
