over inherent methods accessible via more autoderefs.
This simplifies the trait matching algorithm. It breaks code like:
impl Foo {
fn foo(self) {
// before this change, this will be called
}
}
impl<'a,'b,'c> Trait for &'a &'b &'c Foo {
fn foo(self) {
// after this change, this will be called
}
}
fn main() {
let x = &(&(&Foo));
x.foo();
}
To explicitly indicate that you wish to call the inherent method, perform
explicit dereferences. For example:
fn main() {
let x = &(&(&Foo));
(***x).foo();
}

for `~str`/`~[]`.
Note that `~self` still remains, since I forgot to add support for
`Box<self>` before the snapshot.
How to update your code:
* Instead of `~EXPR`, you should write `box EXPR`.
* Instead of `~TYPE`, you should write `Box<Type>`.
* Instead of `~PATTERN`, you should write `box PATTERN`.

The `print!` and `println!` macros are now the preferred method of printing, and so there is no reason to export the `stdio` functions in the prelude. The functions have also been replaced by their macro counterparts in the tutorial and other documentation so that newcomers don't get confused about what they should be using.
bare function store (which is not in fact a kind of value) but rather
ty::TraitRef. Removes many uses of fail!() and other telltale signs of
type-semantic mismatch.
