### Bind expressions
A _bind expression_ constructs a new function from an existing function.^[The
`bind` expression is analogous to the `bind` expression in the Sather
language.] The new function has zero or more of its arguments *bound* into a
new, hidden boxed tuple that holds the bindings. For each concrete argument
passed in the `bind` expression, the corresponding parameter in the existing
function is *omitted* as a parameter of the new function. For each argument
passed the placeholder symbol `_` in the `bind` expression, the corresponding
parameter of the existing function is *retained* as a parameter of the new
function.
Any subsequent invocation of the new function with residual arguments causes
invocation of the existing function with the combination of bound arguments
and residual arguments that was specified during the binding.
An example of a `bind` expression:
~~~~{.xfail-test}
fn add(x: int, y: int) -> int {
ret x + y;
}
type single_param_fn = fn(int) -> int;
let add4: single_param_fn = bind add(4, _);
let add5: single_param_fn = bind add(_, 5);
assert (add(4,5) == add4(5));
assert (add(4,5) == add5(4));
~~~~
A `bind` expression generally stores a copy of the bound arguments in a
hidden, boxed tuple, owned by the resulting first-class function. For each
bound slot in the bound function's signature, space is allocated in the hidden
tuple and populated with a copy of the bound value.
A `bind` expression is an alternative way of constructing a shared function
closure; the [`fn@` expression](#shared-function-expressions) form is another
way.
### Shared function expressions
*TODO*.

Even when a closure takes no parameters, you must still write the bars
for the parameter list, as in `{|| ...}`.
## Binding
Partial application is done using the `bind` keyword in Rust.
~~~~
let findx = bind str::find_char(_, 'x');
~~~~
Binding a function produces a boxed closure (`fn@` type) in which some
of the arguments to the bound function have already been provided.
`findx` will be a function taking a single string argument, and
returning the position where the letter `x` occurs.
## Iteration
Functions taking closures provide a good way to define non-trivial
