Rust

Ah, apparently for now you're not allowed to allocate. But vec::new_in(allocator) looks interesting. This works in nightly today:

#![feature(allocator_api)]

use std::alloc::Global;

fn main() {
    const MY_VEC: Vec<i32> = const {
        Vec::new_in(Global)
    };
    println!("{:?}", MY_VEC);
}

Maybe at some point I can append to it at compile time too. I'd love to be able to put a const {} and have allocations that resolve down to a 'static, and this seems to be a step toward that.

I guess I'm just excited that Vec::new() is the example they picked, since the next obvious question is, "can I push?"
