Here's another use (and apropos a different thread here)

In order to recreate a control you'd want to

1. get the list of properties and their values
2. create a new control of the same type
3. set each of the properties to the original value

One problem with this is that some properties are read-only, and some can only
be applied to the parent object (can't set the rect of a card, for example).

So I do something like

repeat for each element tProp in tPropertyArray
  try
    set the tProp of tNewControl to tPropertyArray[tProp]
  catch e
    -- just ignore the error here
  end try
end repeat
