説明
Once custom attributes are stable, I think it would be great to have an attribute that transforms a for loop into a parallel iterator for_each call:
#[parallelized]
for x in 0..100 {
println!("{}", x);
}
Equivalent to:
(0..100).into_par_iter().for_each(|x| println!("{}", x));
This would be analogous to futures-await's #[async] attribute, which generates a for loop that processes a Stream.
The one nit would be that early returns would be a mistake, hopefully a compiler error, and you would probably want to do what you can to catch them while expanding the attribute.
