Yeah I do expect some very well-written libraries (including standard libraries) to pick it up and use it well, which will benefit a lot of people as these will be widely used libraries, but my guess is most other C++ programmers will not use concepts in nearly as many cases as they hypothetically could/should. Maybe they'll write a few concepts to document the occasional clean interface, but that's about it. The reason being that I expect concepts will have underestimated costs: duplicated logic will not only be frustrating but also get out of sync easily, templates will slow down compilation (it's not like we don't have enough of that already), precise constraints end up being difficult to write, and approximations end up being overly strict/loose and result in headaches for users of a library. They do seem quite beautiful and useful in theory, but I will be very curious to see how much they're adopted. |

For sure! I expect some marquee libraries like ITK to adopt them as soon as it’s prudent (meaning when they can sunset support for older compilers), but most people won’t be using them.
I mean, most people don’t have to even really write templates code...
