How about this: your program uses a logging component. You pass the  
command-line arguments to the logging component, so that it uses getopt to  
pick out the logging options and returns the rest.

One day, the maintainers of the logging component decide to add  
compatibility with Brand X logging component, which uses ':' for the  
equal-sign separator. Naturally the maintainers are sloppy and don't  
restore the option after setting it. You know what happens next...
