> what kind of programming language would a person with as much experience and good taste as Chris Lattner come up with if there were no such external pressures?
That's what the Chris Lattner from back then came up with. I doubt that early Swift is what he would repeat exactly as it was when he would get the chance to do it these days. And current Swift definitely is far away from what he would do, I think he has been quite outspoken about that. So maybe I should make my question more precise and ask what kind of programming language Chris Lattner would come up with in 2026, having learned from all the mistakes that C++, Swift, Mojo (and many others) did?
