@typedef {String} can-stache/keys/current ./current

Lookup a value in only the current context.

@signature `./key`

Only looks up `key` in the current context.  Returns `undefined` if
not found.

```html
{{#each(todo)}}
  <input {($checked)}="./complete"/> {{./name}}
{{/each}}
```

@body

## Use

Sometimes, especially with recursive templates, you want to control which
context is used to lookup.  Adding `./` before the key name will
only look up in the current context.

The following template:

```html
{{first}} {{last}}
  {{#children}}
    {{first}} {{./last}}
  {{/children}}
```

Rendered with:

```js
{
	first: "Barry", last: "Meyer",
	children: [
		{ first: "Kim", last: "Sully" },
		{ first: "Justin" }
	]
}
```

Writes out:

```html
Barry Meyer
    Kim Sully
    Justin
```

Notice that `{{./last}}` returns nothing because there’s no `last` property
in the `{first: "Justin"}` object.
