These are [Variant] value types: [code]null[/code], [bool], [int], [float], [String], [StringName], [Vector2], [Vector2i], [Vector3], [Vector3i], [Vector4], [Vector4i], [Rect2], [Rect2i], [Transform2D], [Transform3D], [Plane], [Quaternion], [AABB], [Basis], [Projection], [Color], [NodePath], [RID], [Callable] and [Signal].
These are [Variant] reference types: [Object], [Dictionary], [Array], [PackedByteArray], [PackedInt32Array], [PackedInt64Array], [PackedFloat32Array], [PackedFloat64Array], [PackedStringArray], [PackedVector2Array], [PackedVector3Array] and [PackedColorArray].
