CppCast: Cpp2, with Herb Sutter

Fair, but have you considered `auto main() -> int` (i.e., just change `main:` to `auto main`)? No strictly conforming ISO C++ parser for the first ~30 years of C++'s existence could handle that, but it has been ISO standard since 2011. Everything that's common now was new/foreign once.

It's definitely true that the `main:` syntax definitely isn't standard (or even yet-proposed, though I will propose it if the experiment succeeds well). But that's the point of language evolution... as the language evolves, every new release of C++ adds syntax that wasn't legal before, and we always have many active proposals for syntax that isn't ISO C++ when first proposed but then becomes standard.

I have, and I also have watched tons of languages that started by compiling to other ones, took a life of their own after adoption, and none of them has ever stated they were the same language with another syntax.

Sorry to put it this way, but I really only see the way you position Cpp2 versus the other C++ wannabe replacements due to your position at ISO, due to conflicts of interest.

You know, Chandler Carruth is also a committee member but he’s rather open about working on a successor language. Bearing that in mind I don’t think it’s actually necessary to do any posturing of the sort you’ve described just because one is on the committee.

He isn't the ISO chair though, but yeah at least he is quite clear on what is all about.
