Do you have numbers for how much of the web avoids variable hoisting? How much of the web has more than one top-level fn per file? Do these numbers shift significantly between different toolchains or methods of delivering JS?

How is partial execution baked into JS? IIUC, my whole JS file is fully parsed an resolved before it is evaluated. If you're referring to the use of multiple files for parallelism here, then the obstacle there is not wasm itself but th

It would be interesting to try for some apples-to-apples comparisons for the parse and initial exec time of js vs wasm. The latter was designed with the goal of streaming validation and compilation, js needs to have a lot of work done befor

Many types in the standard library do not consider it sound behavior to have their allocations freed by functions other than their own destructors: https://doc.rust-lang.org/std/boxed/struct.Box.html#method.i...

Re: non-thread-safe items in lazy_static, you can also wrap them in a mutex within just the lazy_static so the struct only uses synchronization when it actually needs to be thread-safe.

Rust's built-in lints are configurable with compiler directives, so you'll be able to add #![deny(bare_trait_objects)] To the top of your crate and cause a compiler warning if someone uses the old syntax on your project.

There's not a lot of consensus about what primitves good *-native framework needs, implementations are often pretty tied to specifics of the JS libraries they were built to be driven by (go figure), and the whole niche is still discove

FWIW, I read "To an outsider..." to mean "if you are reading this on HN and aren't involved in the community, this might seem like" as opposed to "I am pretending to be an outsider, let me tell you what about m

I'd actually be interested to find out how Cargo's performance compares in a situation as TheDong describes where all of the dependencies are being fetched directly from git. Part of me wants to say "well of course Rust'

I tend to agree, but I also think that there's a little bit of nuance here. For one thing, I have definitely enjoyed using a large standard library...when I didn't have access to cargo or tools of similar quality. My impression is

I recently found myself inserting &/*/ref/ref mut into match expressions before I'd even seen a compiler error. My first thought was "aha, look at how experienced I am with Rust now!" Followed immediately b

One might assume that not every user of HN has the same beliefs and motivations as the others.

The path to stabilizing explicit simd intrinsics for rust should make many of those kinds of errors easier to catch with rusts casting requirements.

Awesome! It looks like they have some tests in the directory -- I'd be curious whether they're able to re-use musl's test suite some. I had an experiment a while ago to incrementally port musl to rust while keeping the test s

Like any situation in software, there are likely to be tradeoffs. I certainly wouldn't advocate for launching large rewrites except under extreme duress. That said, I'm not sure I agree with how you're characterizing the trad

I suspect that given Facebook's history with patents it has probably been in the works a long time to make this change.

Yeah I think this is fair. Although it might have helped to preface with that. Nonetheless, a small amount of egg on my face.

Since it wasnt clear from my post above, I buy all of this. But since IANAL, and I couldn't easily find a credible patent lawyer who has written publicly about this, I think it's reasonable to be measured in the claims I made. Tha

Some are of the opinion that MIT includes an implicit patent grant/license. Googling around I don't see many references to support this, but there are a few: * http://en.swpat.org/wiki/Implicit_patent_lic

For clarification, "trait objects" are a subset of the trait system, and have much less use in rust programs than traits overall. A trait object is a dynamically dispatched pointer (often owned through Box or Arc), as opposed to t
