Wwwwweeeeellllllllllll, that's not strictly true. If you have globals
turned on, and define something as global, then won't it be visible
outside the function? If you define a session variable (super-global)
inside a function, doesn't it retain its value outside the function?
OK, I know that is not what you meant, but your statement is not exactly
100% accurate as written when read by and independent reader.
