* `use mod` is no longer valid.
* `fail!` and `assert!` accept `~str`, `&'static str` or `fmt!`-style
argument list.
- * `Encodable`, `Decodable`, `TotalOrd`, `TotalEq`, `DeepClone` can all
- be automatically derived with `#[deriving(...)]`.
+ * `Encodable`, `Decodable`, `Ord`, `TotalOrd`, `TotalEq`, `DeepClone`,
+ `Rand`, `Zero` and `ToStr` can all be automatically derived with
+ `#[deriving(...)]`.
* The `Durable` trait is replaced with the `'static` bounds.
* At long last, 'argument modes' no longer exist.
* The `bytes!` macro returns a vector of bytes for string, u8, char,
`(0, 1, 2).n2()` or `(0, 1, 2).n2_ref()`.
* std: many types implement `Clone`.
* std: `path` type renamed to `Path`.
- * std: Many standalone functions removed in favor of methods in
- `vec`, `str`. In the future methods will also work as functions.
+ * std: Many standalone functions removed in favor of methods and iterators
+ in `vec`, `str`. In the future methods will also work as functions.
* std: `reinterpret_cast` removed. Used `transmute`.
* std: ascii string handling in `std::ascii`.
* std: `Rand` is implemented for ~/@.
* std: `Cell` constructors converted to static methods.
* extra: `rc` module adds the reference counted pointers, `Rc` and `RcMut`.
* extra: `flate` module moved from `std` to `extra`.
- * extra: `FileInput` implements `std::io::Reader`.
+ * extra: `fileinput` module for iterating over a series of files.
* extra: `Complex` number type and `complex` module.
* extra: `Rational` number type and `rational` module.
* extra: `BigInt`, `BigUint` implement numeric and comparison traits.
* `Clone` and `DeepClone`, to perform (deep) copies.
* `IterBytes`, to iterate over the bytes in a data type.
* `Rand`, to create a random instance of a data type.
+* `Zero`, to create an zero (or empty) instance of a data type.
* `ToStr`, to convert to a string. For a type with this instance,
`obj.to_str()` has the same output as `fmt!("%?", obj)`.
