* Units from <ratio> are no longer redeclared in our own namespace * The default clock is `steady_clock`, not `high_resolution_clock`, because, as HH says "high_resolution_clock is useless. If you want measure the passing of time, use steady_clock. If you want user friendly time, use system_clock". * Benchmarking support is opt-in, not opt-out, to avoid the large (~10%) compile time penalty. * Benchmarking-related options in CLI are always present, to decrease the amount of code that is only compiled conditionally and making the whole shebang more maintainble.
