A very nicely presented workaround for the lack of PBR.
Whats remarkable is the hoops you must jump through.
Your example using this version of PBR:

function list.addItem(object item)
        append(list, item)
    end function
   function list.getItemIdx(object item)
    -- PBR not needed for this fct, but what the heck
        return find(item, list)
    end function


    procedure main()
        sequence myCars, myPhones, myGirlFriends
        atom idx
        myCars = {}  myPhones = {}  myGirlFriends = {}
--? do I need these inits?  why?   how do I put them in addItem()?

        mycars.addItem("Porche")
        myPhones.addItem("123-456-7890");
        myGirlFriends.addItem("Jennifer Aniston")
        -- no reason for another way to add items
 
        -- get the index
        mycars.add("Porche")
        idx = mycars.getItemIdx("Porche")
        -- again, other ways are not needed or desireable
    end procedure

A remarkable increase in brevity and clarity (and faster).
