Actually, method matching selector is an example of _not_ breaking. DNU 
(Does Not Understand) is a bit too powerful for most cases -- kinda like 
swatting flies with a sledge hammer rather than a fly swatter.  Best 
used carefully!

Good to know about, however.  Sometimes the solution _is_ to use a 
bigger hammer!
