So I'm only a Rust amateur (I mean I don't get paid to use it), but I'm on my third round trying to build something with it, and I feel like I'm finally starting to get it. A couple warts I've encountered:
- No support for default struct fields: https://github.com/rust-lang/rfcs/issues/1594
- Terrible signatures for functions that return iterators: https://www.reddit.com/r/rust/comments/2h26cj/functions_retu...
If the next push is going to be for ease-of-use, those would be two nice things to fix.
A feature designed as a fix for the second problem is already in nightly:
https://github.com/rust-lang/rust/issues/34511
Who knows when it'll be stabilized, though.

"sooner rather than later"
I think if you don't mind the overhead you can box the iterator

Agreed, and Vec should just be Buf! Let's fork the language. :)
And it should be white-space sensitive!
1. Writing a tab character introduces the equivalent of {} for blocks, but not other uses of {}.
2. You can still use {} for blocks if need be
3. Everyone uses elastic tabstops in their editor
> parens are optional for function application
I think you've gotten confused somehow... Rust++ is a pure concatenative programming language, function application is wholly unnecessary.
Stop, I can only get so hard before an unsafe drop in blood pressure
Why not rename Vec to Buf everywhere with a Vec = Buf type alias for backwards compatibility?
Why not rename String to StrBuf everywhere with a String = StrBuf type alias for backwards compatibility, if this would clarify new users' understanding of String/str?

It's not clear that there's a ton of benefit, and not everyone agrees with me that StrBuf is a good name.
I see. I hope to see more better docs soon. Thank you for answering and for generally being open.

You're welcome, on both counts. I hope we can help you not get stuck if you give it a fourth try :)
I'm not sure enough time has passed to tell what Rust's warts truly are. I always joke String should have been called StrBuf...
I do this, yes. This is one of the reasons I hang out in IRC so often; it's an effective way to collect these kinds of things.
More data is always better, and collecting it across multiple venues. I don't think IRC is inherently going to be a representative sample. It's one of the reasons you'll see me pushing for details in Rust threads here, for example.
