Rust: A Critical Retrospective
> we did not have Vec because we were no-std + stable so we literally had to use arrays
It's true that Vec isn't available in a no-std context, but don't think it follows that arrays are the only other option - see heapless for one example: https://github.com/japaric/heapless
I also agree with some of the ancestors: the post seems to say that the Rust language couldn't handle arrays with more than 32 elements, and (as someone who's written a fair bit of no-std Rust before const generic) that doesn't seem right. At first, this did seem awkward to me as well, but in practice I haven't found it to be a significant limitation. Was there a particular scenario where it wasn't feasible to wrap a >32 element array in your own type and implement Default on it?

Now that the long-awaited const generics (MVP) have come to stable in 1.51, what crates are going to gain the most from it?
