And, I am very happy that, in lengthening the opening and closing quotes, we are making it possible to paste an arbitrary sequence of unicode without having to hunt around inside the sequence to find stuff that needs extra quoting, as is the case with today's strings.
That's the high order bit here; paste an arbitrary snippet.
The thing we are discussing here, the need to give special handling to leading and trailing backticks is (crucially) an edge effect (only at the two ends of the string) and not a bulk effect (something that needs attention throughout the string). That means we have won on the key issue, and are just disagreeing about how to collect our winnings.
I already collected my winnings, and am now spending them in the bar. Join me for a drink :)
