-Using `as` operator works consistently regardless if `InterfacedVarialbe` is declared as a class instance (like `TSomeClass`) or interface (like `ISomeInterface`). However, casting an interface to another interface this way is not allowed under `{$interfaces corba}` - we will cover that topic later.
