Feature request: Drop the iter() from vec.

[sandeep-datta]

Please consider dropping the additional call to iter() in the following code...

let vec = vec![1i, 2i, 3i];
for i in vec.iter() {
    println!("{}", i);
}

Preferred...

for i in vec {
    println!("{}", i);
}

Changes such as this require an RFC, and this is actually enabled by this RFC's design of Iterable: rust-lang/rfcs#235. I'd recommending watching that to get updates on it!
