I do not know about you, but I think this is not only shorter (in spite of 
adding a helpful error message), but also simpler to understand (not using 
convoluted do { } while logic), and therefore superior.

Your performance argument is weak IMHO, as this is not a big performance 
hit, and command line parameter parsing is definitely not performance 
critical.
