I'm not sure I'd want it removed, but generics tend to be pretty horrific looking to people new to the language.

An example:

  fn largest<T>(list: &[T]) -> T {
    let mut largest = list[0];

    for &item in list.iter() {
        if item > largest {
            largest = item;
        }
    }

I'm sure experienced Rust devs look at that and say it's fine, but that's definitely a hurdle for new developers.

You need to specify the properties of T that you use. So, that first line should be:

  fn largest<T: PartialOrd + Copy>(list: &[T]) -> T {

What would you want to see instead? That's pretty much the same syntax as generics in Java.
