There are a mind-boggling large number of things that are useful, 
but that's not the criteria for adding something to a programming 
language.

A new feature has to be *sufficiently* useful to justify the 
increased complexity of the language and it's implementations 
(plus not clashing badly with other features). Example use cases 
are a useful way of demonstrating just how useful a feature can 
be.
