An example would really help to get started.

I tried to write an example to convert futures2 to futures1 including async and await macros: https://gist.github.com/manuels/d6a7d33f3a566a62c33cbd77bdf309a8

PS: it could be a little overcomplicated with the __rt module, but I didn't have a better idea to make it work

You run into a problem if you want to use futures v0.1 and futures v0.2 in the same program: Cargo will only allow you to use one of them because of the name clash (I am talking about futures v0.2, not futures-core v0.2).

You could circumvent this problem if futures-compat would change a single line in lib.rs:

- extern crate futures;
+ pub extern crate futures;

In that case the programmer could use these dependencies for his programm:

[dependencies]
futures-compat = "*"
futures = "0.2.1"

and still use both Future types in the program (including async and await macros):

extern crate futures_compat;
extern crate futures;

use futures_compat::futures::Future as Future1;
use futures::Future as Future2;
