#### Definition Scope
You can set the scope of a definition by setting the `scope` property on the definition.
For example, a javascript function declaration creates a scope. The function name is captured as the definition.
This means that the function definition would only be available WITHIN the scope of the function, which is not the case.
The definition can be used in the scope the function was defined in.
```javascript
function doSomething() {}
doSomething(); // Should point to the declaration as the definition
```
```scheme
(function_declaration
((identifier) @definition.var)
(set! "definition.var.scope" "parent"))
```
Possible scope values are:
- `parent`: The definition is valid in the containing scope and one more scope above that scope
- `global`: The definition is valid in the root scope
- `local`: The definition is valid in the containing scope. This is the default behavior
