Steve seems like a genuinely helpful guy, but I'm not sure my most recent headache is a documentation problem so much as a deficiency in the std/core library. I was trying to write a generic function that called abs() on some of

You're interested in the links, not the arguments. I can't see how this is going to be fruitful.

I've had several discussions with you over the last couple years. I create throw away accounts on Hacker News, Stack Exchange, Reddit, Slashdot, Rust Users, and so on because I value my privacy. I don't want to tie my throw away

I like generics as well, but this comment (and embedded links) made me appreciate why Go doesn't have them yet: https://news.ycombinator.com/item?id=9622417 I agree, the value in generics/templates is in not

Are you only asking the person you replied to? I have some topics I think indicate shortcomings in the language itself, but when I've brought these to the attention of core Rust developers in other threads of discussion the result has

Are Servo and rustc in the Rust documentation? Literate programming of some sort? Maybe you're replying to a different criticism. I've been through the Rust Documentation (doc.rust-lang.org) and Rust By Example (rustbyexample.co

> Rust is a formalization/codification of idiomatic C++ Idiomatic C++ favors values and copy semantics. Rust favors references and move semantics. C++ has function and method overloading, and Rust does not. There are so many plac

Same reason paleontology, geology, anthropology, climate science, astronomy, and so on have a difficult time... Any theory that can't be falsified by running an experiment shouldn't be called "science". At best, people

Being motivated and not quitting are very different things. I like the work I do, and I work hard at it. However, other places have interesting problems too, and if I could find a place that pays me more than I make now, I'd jump.

It needs to compile (at least the C or C++ parts). Frequently the people who operate the software will want to make small changes.

It gets worse. My software has to run on my customer's computers. These can be any of RHEL 5, 6, or (rarely) 7. It'll be a few years before I can safely deliver C++ 11 software, and I snicker at the Pythonistas complaining abou

We were talking about reading into a bounds checked array. Rust does not user iterators for this.

Completely agree. The same is true at a slightly higher level in C++. All of the "dangling reference" problems can be avoided by using a value-based collection library and not creating references. Then upgrade to a unique or sh
