Also notice that $$foo{bar} ... notice the doubled dollar-sign ... is equivalent to $foo->{bar}.   The potential problem being of course that a single dollar-sign in this case is also syntactically valid but carries a different meaning.   The best thing to do is to adopt a “shop standard” and then stick to it very religiously.   “PARIS IN THE THE SPRING” and all of that ... heh ... you did see the extra word in there, now, didn’t you?
