### Unary copy expressions

~~~~~~~~
> **Note:** `copy` expressions are deprecated. It's preferable to use
> the `Clone` trait and `clone()` method.
A _unary copy expression_ consists of the unary `copy` operator applied to
some argument expression.
Evaluating a copy expression first evaluates the argument expression, then
copies the resulting value, allocating any memory necessary to hold the new
copy.
[Managed boxes](#pointer-types) (type `@`) are, as usual, shallow-copied,
as are raw and borrowed pointers.
[Owned boxes](#pointer-types), [owned vectors](#vector-types) and similar owned types are deep-copied.
Since the binary [assignment operator](#assignment-expressions) `=` performs a copy or move implicitly,
the unary copy operator is typically only used to cause an argument to a function to be copied and passed by value.
An example of a copy expression:
~~~~
fn mutate(mut vec: ~[int]) {
vec[0] = 10;
}
let v = ~[1,2,3];
mutate(copy v); // Pass a copy
assert!(v[0] == 1); // Original was not modified
~~~~
### Unary move expressions
~~~~~~~~{.ebnf .gram}
move_expr : "move" expr ;
~~~~~~~~
A _unary move expression_ is similar to a [unary copy](#unary-copy-expressions) expression,
except that it can only be applied to a [local variable](#memory-slots),
and it performs a _move_ on its operand, rather than a copy.
That is, the memory location denoted by its operand is de-initialized after evaluation,
and the resulting value is a shallow copy of the operand,
even if the operand is an [owning type](#type-kinds).
> **Note:** In future versions of Rust, `move` may be removed as a separate operator;
> moves are now [automatically performed](#moved-and-copied-types) for most cases `move` would be appropriate.

By default, type parameters do not carry any assumed kind-bounds at all.
When instantiating a type parameter,
the kind bounds on the parameter are checked
to be the same or narrower than the kind
of the type that it is instantiated with.
Any operation that causes a value to be copied requires the type of that value to be of copyable kind,
so the `Copy` bound is frequently required on function type parameters.
For example, this is not a valid program:
~~~~{.xfail-test}
fn box<T>(x: T) -> @T { @x }
~~~~
Putting `x` into a managed box involves copying, and the `T` parameter has the default (non-copyable) kind.
To change that, a bound is declared:
~~~~
fn box<T: Copy>(x: T) -> @T { @x }
~~~~
Calling this second version of `box` on a noncopyable type is not
allowed. When instantiating a type parameter, the kind bounds on the
parameter are checked to be the same or narrower than the kind of the
type that it is instantiated with.
