I was not speaking formally, but the idea is that a symbol is the thing itself (the things in the symbol table), and it may be referred to by different names, or even no name at all if it is anonymous.

More formally, =:= is used to compare item containers, since normally anything you do to an item drops through to the item in the container. $x =:= $y is just a shortcut for VAR($x) === VAR($y).
