Godot 4.5 - varargs

Godot 4.5 added support for functions with variable number of arguments. Also known as variadic functions. They look like this:

func warning(...msg: Array) -> void:
	var message: String = " ".join(msg.map(str))
	print("WARNING |", message)

• You can put some other arguments before the variadic one. Similar to Python’s *args, **kwargs - those have to be at the end too
• The type of the variadic argument has to be an untyped Array

People have been asking for them for literal years, so even now when I google Godot varargs function, the top result says they are not supported. Well - they are now! See more examples here!
