I am not personally making any prediction whatsoever on whether we will
ever get HORSE or not; I do not have any secret agenda! :) If this kind
of proposals are useful to spur old discussions, by all means, let's
have them. (But in another thread :-P. By the way, P1163 got rejected).

My *strong* position is: there are plenty of legitimate, non-niche use
cases for initializer lists that don't have the HORSE problems. These
initializer lists are already usable with certain stdlib functions, but
they're not usable with other functions (sometimes strongly related,
e.g. push_back/erase) because of an oversight. My aim is to simply close
that oversight. I definitely do not believe that improving this CART is
going to increase the adoption of "wrong" usages so much that this will
effectively block any future tentative of fixing the HORSE.

Thanks for your feedback, stay safe,
