...
Until some backwards-compatibility hazards are fixed in #23121 ,
these need to be unstable.

Switch to purely namespaced enums
...
This breaks code that referred to variant names in the same namespace as
their enum. Reexport the variants in the old location or alter code to
refer to the new locations:
```
pub enum Foo {
A,
B
}
fn main() {
let a = A;
}
```
=>
```
pub use self::Foo::{A, B};
pub enum Foo {
A,
B
}
fn main() {
let a = A;
}
```
or
```
pub enum Foo {
A,
B
}
fn main() {
let a = Foo::A;
}
```

librustc: Change the syntax of subslice matching to use postfix ..
...
instead of prefix `..`.
This breaks code that looked like:
match foo {
[ first, ..middle, last ] => { ... }
}
Change this code to:
match foo {
[ first, middle.., last ] => { ... }
}

librustc: Remove the fallback to int for integers and f64 for

floating point numbers for real.
This will break code that looks like:
let mut x = 0;

x += 1;

println!("{}", x);
Change that code to:
let mut x = 0i;
while ... {
x += 1;

println!("{}", x);

Rewrite exhaustiveness checker
...
Issue #352
Closes #1720
The old checker would happily accept things like 'alt x { @some(a) { a } }'.
It now properly descends into patterns, checks exhaustiveness of booleans,
and complains when number/string patterns aren't exhaustive.
