I disagree. If it is a 'const object' then it must have been
declared so, otherwise it must be something other than a
const object. Ask a bunch of grammarians if 'not declared object'
refers to 'that object' or 'a pointer to that object', and I bet
the majority will answer 'a pointer to that object'. If any
grammarians E-mail me their opinions, I will post a summary to
the net (but only if I'm proved right, of course :-) ).
