A similar one I have seen: "If a messy desk is the sign of a messy mind, what is an empty desk the sign of?" ;-)

>>You made it clear - "most of the people..."; no confusion there. Was just thinking aloud as to why I don't think that's a healthy practice. If you are sure the variable will be so very local, then fine - I do that sometimes myself. But as a general habit, spreading declarations all over the place looks sloppy to me. Looks almost like my desk.
