10// The old protocol used a constraints() member function in concept
11// checking classes. If the compiler supports SFINAE, we can detect
12// that function and seamlessly support the old concept checking
13// classes. In this release, backward compatibility with the old
14// concept checking classes is enabled by default, where available.
15// The old protocol is deprecated, though, and backward compatibility
16// will no longer be the default in the next release.
