Shorthand for export nodes

[ghost]

Problem:
When using an exported node in a scene, it is common practice to write two lines: one for the export, and another for loading the node.

For example, if you wanted to use a Camera node from your scene, you would probably do this:

export(NodePath) var camera_path
onready var camera : Camera = get_node(camera_path)

This method wastes an extra line for every exported node! This is not good enough.

Solution:
There is a lesser-known method for using exported nodes in one line. For example, the shorthand for the code written above would be this:

export(NodePath) onready var camera = get_node(camera) as Camera
