If the component used the "is" operator it wasn't using the full RTTI.
With the full RTTI you don't need to know rather a component is a TLabel
or TMemo. You can simply ask "does this component have a Left property?
Is that property an integer?" and save the property's value if it
exists! On the other hand using the "is" operator you may gain access to
fields that are not properties, but that's not as interesting.
