Never.  In fact it took me a while to understand what you meant.  :-)

The code is compiled as

^(##(CFunctionDescriptor for: 'SDL_Flip' returning: #int
        args: #( #cObject ))
                callInto: ValueHolder now) value

Where "descr callInto: ValueHolder now" is supposed to return its argument.
