It would be quite abnormal to run getopt multiple times in the same

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...
Sloppy maintainers may also take the GetOpt object by reference, change
its state, and pass it back.
