I suggested that before, but apparently 2013 was not the right time to suggest standardizing the interface without adding an implementation to the stdlib; maybe things are different enough in 2015. Thanks for raising the idea. I'll go back and try to dig up other past proposals and re-survey the different options to see if that seems plausible, and meanwhile I'll stop derailing this thread with it. :)
