I'm not sure that's the case, or if it is, those programs will suffer 
significantly from using an alternative (the most obvious alternative is 
to allocate those particular cases on the heap).

Consider the other problem. It's not easy for a human to look at 
Steven's case and verify that it is correct. A small mistake in it, and 
it isn't correct anymore. What's it worth to be rid of such problems?
