The "Juicy Main" looks like a very nice QoL feature. Gets rid of all the boilerplate for allocators and argv.
It's the dark horse of this release as CLI parsing can also be more easily built on top of it. There's a couple of proposals floating around now, so I hope we get something soon-ish (maybe in 0.18 since a short cyle is planned for 0.17).
Do I get it right that this is everything you need for a typical CLI tool?
