		Reference to a function in an object.
	</brief_description>
	<description>
		In GDScript, functions are not [i]first-class objects[/i]. This means it is impossible to store them directly as variables, return them from another function, or pass them as arguments.
		However, by creating a [FuncRef] using the [method @GDScript.funcref] function, a reference to a function in a given object can be created, passed around and called.

			<argument index="0" name="arg_array" type="Array">
			</argument>
