We have yew, and my personal favourite: leptos (https://leptos.dev/)
Interesting that tail calls are mentioned and implied to never come to Rust. I agree with your assessment and actually there is a RFC[1] in the works to support them. (Note that while I'm the author, this RFC is definitely a community effort.)

I think its cppfront that is taking the approach of `:=` being a declaration with the type being inferred (ie shorthand for `: Type =`). Reading up on that has made me the most ok with applying this to functions (which I see coming up more these days) but I think i still prefer functions having a more distinct look as I process them differently when reading. Now, cppfront's approach to types I think is bonkers, making critical details hard to find except maybe through convention.

> <> for inequality is something SQL got right
Maybe I'm not recognizing the biases of my own learning background but this never reads right to me vs "not equal" / `!=`.
> - concise keywords like `fn`
In other discussions, it sounded like Graydon had an upper limit of 4 characters for keywords

For me, I had a "whoosh" moment for `fn` and always thought it a weird abbreviation, completely overlooking "fn" keys on laptops.
Perhaps you'd be interested in Inko (https://inko-lang.org/). It's obviously not there yet in terms of tooling and what not, but it might scratch an itch for those looking for something a bit like Rust, but easier to use.
Disclaimer: I'm the author of said language :)
"Exterior iteration. Iteration used to be by stack / non-escaping coroutines, which we also called "interior" iteration, as opposed to "exterior" iteration by pointer-like things that live in variables you advance. Such coroutines are now finally supported by LLVM (they weren't at the time) and are actually a fairly old and reliable mechanism for a linking-friendly, not-having-to-inline-tons-of-library-code abstraction for iteration. They're in, like, BLISS and Modula-2 and such. Really normal thing to have, early Rust had them, and they got ripped out for a bunch of reasons that, again, mostly just form "an argument I lost" rather than anything I disagree with today. I wish Rust still had them. Maybe someday it will!"
I remember that one. The change was shortly after I started fooling with Rust and was major. Major as in it broke all the code that I'd written to that point.
"Async/await. I wanted a standard green-thread runtime with growable stacks -- essentially just "coroutines that escape, when you need them too"."
I remember that one, too; it was one of the things that drew me to the language---I was imagining something more like Pony (https://www.ponylang.io/).
"The Rust I Wanted probably had no future, or at least not one anywhere near as good as The Rust We Got."
Almost certainly true. But The Rust We Got is A Better C++, which was never appealing to me because I never liked C++ anyway.
The compiler won't choke, but it will stop you from accessing the value.
It doesn't matter if you omit the `else` clause or not, the type system ensures that you can't access invalid values.
Here's a bit of an example based off of @Ygg2's code: https://play.rust-lang.org/?version=stable&mode=debug&editio...
I've just been browsing, eg., https://github.com/robot-rumble/logic/blob/master/lang-runne...
Have a look at real-world rust repos that are more than simple application code.
Personally, I feel like I'm being visually assaulted.
