[This fails to compile](https://is.gd/GyNDt8). The error is that a `&` is required on the last line of `main`: `let w = &(...) ^ &z;` The error message seems to indicate that the inner operation is wrong, when in fact it is the outer one which needs correcting: ``` <anon>:15:14: 15:21 error: binary operation `^` cannot be applied to type `A` [E0369] <anon>:15 let w = (&x ^ &y) ^ &z; ^~~~~~~ ``` should (in my opinion) read: ``` <anon>:15:14: 15:21 error: binary operation `^` cannot be applied to type `A` [E0369] <anon>:15 let w = (&x ^ &y) ^ &z; ^~~~~~~~~ ``` Checked on `rustc 1.10.0-nightly (6974800c6 2016-05-08)` and an older nightly.
