Godot version

System information

Godot v4.1.stable - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1050 (NVIDIA; 31.0.15.3667) - Intel(R) Core(TM) i5-8300H CPU @ 2.30GHz (8 Threads)

Issue description

If you define a class_name and then use the same name in a variable, no shadowing error/warning is triggered. This also create some bad references (see below).

Steps to reproduce

Just do something like:

class_name Foo
extends Control

var Foo: Foo

In another script you can also do:

extends Node

var Foo: Foo #= Foo.new() # this raises an error if uncommented: Parse Error: Could not resolve member "Foo": Cyclic reference


func _ready():
	Foo ## This refers to main.gd and not to the local variable
