Indeed. I haven't found concepts to be very good at generating error messages. But they are great for documentation and to get rid of SFINAE hacks for overloading. The shorter template syntax is a bonus. edit: concepts should also allow for better IDE tooling, for example proper completion inside template functions; although it is supposed to work, I didn't notice it firing yet in clangd.
