Assigning a bool to modulate.a (color alpha) works in debug if declared but not in release.

Issue description

The title pretty much explains it.

This works is debug but not in release:

extends Node2D

onready var icon = $Icon as Sprite

func _ready() -> void:
    icon.modulate.a = false

However if you don't declare and simply assign it, you do get the error of assign type bool to an alpha color.

extends Node2D

func _ready() -> void:
    $Icon.modulate.a = false

I don't know what is intended, if this should fail or not, but it should at least be consistent in both debug and release.

Steps to reproduce

1. Drop the icon.png into a 2D scene
2. Assign a script to the scene and declare the icon
3. In _ready set the icon's modulate alpha to false
4. Export a release build and compare

I have attached a simple project .zip with a windows release build in its project folder.

Can you reproduce this on 3.5.rc4? Type information is now included in release builds, so this kind of typing discrepancy between release_debug (editor) and release builds should be gone now.

Yes it works in 3.5.rc4. Thanks!

However, it highlights a difference when writing gdscript in general, should it throw an error when you don't declare it and work fine if you do?

onready var icon = $Icon as Sprite

func _ready() -> void:
   # Works
   icon.modulate.a = false

   # Gives error
   $Icon.modulate.a = false

Or should we just convert the type in script int(false), and avoid these little things? Just incase Godot under the hood doesn't just do it for you.
