Is there a way to modify scenes programatically?

Question

For example, I incorrectly named a bunch of nodes, is there a way to rename them all with a script?

A repl for the editor would be really cool actually ...

Sure, just load your scene and do your changes on an instance of it. Then you can save it back to the disk resource using ResourceSaver.save().

Short example:

var scene_path = "res://my_scene.tscn"
var scene = load(scene_path)
var root = scene.instance()
for node in root.get_children():
    node.set_name(new_name)
scene.pack(root)
ResourceSaver.save(scene_path, scene)

Even though the OP didn't say thanks I'd like to. That's great help for something I'm facing at present.
