range() return value should be typed as Array[int] instead of Array

[gitsomebit]

Tested versions

4.3 stable

System information

Godot v4.3.stable - Windows 10 - GLES3 (Compatibility)

Issue description

I am always using typed variables as a best practice. In my code I wanted to use the following code:

var display_monitors: Array[int] = range(DisplayServer.get_screen_count())

This throws an error on assignment, because range() always returns and untyped Array even though its always an Array[int]. The docs even indirectly mention that only ints are returned:

range() converts all arguments to int before processing

To iterate over float, convert them in the loop.

Steps to reproduce

just assign range to an typed array and it fails:

var var_name: Array[int] = range(3)

See:

• Built-in range function returns Array instead of Array[int] #87152
• Make range() return Array[int] instead of an untyped Array godot-proposals#9277

This would break compatibility

thanks for the fast reply.
I will leave this issue open for now as it seems there are more people that get hung up on it. Since this would break compatibility for cases such the following example it might be interesting for 5.x

Example

func _ready() -> void:
	var some_array: Array = new_range()
	some_array[0] = "asdf" # error
	some_array.append("asd") # error
	print(some_array)

func new_range() -> Array[int]:
	return [1,2,3]
