Custom Type Object reference inside Function

That's not true

Local lista:TList = New TList
lista.AddFirst("Hello")
Print lista.Count()
ChangeList(lista)
Print lista.Count()
ChangeList2(lista)
Print lista.Count()

Function ChangeList(list:TList)
	list = New TList
End Function

Function ChangeList2(list:TList Var)
	list = New TList
End Function

the output of this code is:


if they were passed always by reference, the output would be


the objects are passed by value, but having the value of an object lets you change its fields and use its methods and functions, etc.
