I know that, one day, I have to write a counter-proposal to the Operator proposal that hit WG14's desk. (https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3051.pdf)
I'm mostly in support of it, but the author seems bullish on some details. I'm gonna have to try to hit back gently but with conviction about the design space here...
