They're included in Rust. But Rust of course feels very much like a strict-by-default Haskell in some ways.

(Now with optional laziness.)

i had no idea rust supported laziness! how does that work?
I think he refers to async recently landing in Rust.

Here the Rust book mentions it:

> async bodies and other futures are lazy: they do nothing until they are run.

I just read it, and thought it was odd. I don't understand how Rust's async relates to a laziness as in Haskell's laziness.

Iterators are also lazy.

All of these things build up some form of computation that doesn’t execute until later. Until then, they’re represented by some kind of data structure.
