That was the idea, yes, in particular to make it similar to "+", which adds to the end of the string, so that: s = x - oldend + newend works as expected. > I don't think x~y is intuitive enough to use. True. I tried to find an operator that looked similar to "-", but "~" would only work as unary operator, a Chris correctly pointed out, and even if it were a binary one, it would look too similar to "-" and also doesn't play well when used on a single line. s = newstart + (x ~ oldstart) So I withdraw that proposal. > On Wed, Oct 13, 2021 at 8:03 AM Stephen J.
