// checking classes.  If the compiler supports SFINAE, we can detect
// that function and seamlessly support the old concept checking
// classes.  In this release, backward compatibility with the old
// concept checking classes is enabled by default, where available.
// The old protocol is deprecated, though, and backward compatibility
// will no longer be the default in the next release.
