If I understand correctly, placeholders may work for this. This use is described in the "Programming with placeholders" section of the "Introducing concepts" article: https://accu.org/index.php/journals/2157

The remaining articles in Andrew Sutton's C++ concepts series are pretty good, too; so, just in case anyone is interested, here are the links:

- "Defining Concepts" - https://accu.org/index.php/journals/2198

- "Overloading with Concepts" - https://accu.org/index.php/journals/2316

If I understand the first article about placeholders correctly, concepts are indeed intended to be used where you can use ordinary types, just like traits. That looks really cool, if it ends up in the standard.
