How to access fields in GDScritp from Nim?
Two people on discord told me `get("property_name")` works in C++, D, etc, so I am assuming it should work in Nim as well, but it didn't. From my current test project:

In Data.gd (autoloaded as "data") 
```gdscript
extends Node

export fov_radius = 42  # export isn't needed here, I just tested this with/without it
```

Then in a Nim file

```Nim
let data = self.get_tree().root.get_node("data")
print(data.get_class()) # >>> Node

print("fov_radius: ", data.get("fov_radius")) 
# runtime error: Unhandled Nim exception (NilAccessError): Could not access value because it is nil.
```

How can I make it work?

(Note: I don't necessarily need this only to access autoloaded scripts, I might want to get access to something else.)
