Can define a method twice in a trait impl

[huonw]

struct Foo;

trait Bar {
    fn bar(&self) -> int;
}
impl Bar for Foo {
    fn bar(&self) -> int {1}
    fn bar(&self) -> int {2}
}

fn main() {
    printfln!(Foo.bar())
}

$ rustc double-def.rs
$ ./double-def
1

struct Foo;

trait Bar {
    fn bar(&self) -> int;
}
impl Bar for Foo {
    fn bar(&self) -> int {1}
    fn bar(&self) -> int {2}
}

fn main() {
    println!("{}",Foo.bar());
}

$ rustc 8153.rs
$ ./8153
$ 1

When I tested with this code based on reporter's code, It still shows same result.

I could've sworn I had fixed this in c6f3103 :(

The logic seems to have changed in resolve since then and even though it still seems to catch this case:

impl Bar {
    fn bar(&self) -> int {1}
    fn bar(&self) -> int {2}
}

The error message got less descriptive:
error: duplicate definition of value bar``

vs what it used to be:
error: duplicate definition of method bar``
