So Perl intertwines expectations about behaviour with syntax.

Quick, what does $bar = $foo{bar} mean? What does it do? How do you know, you've just seen syntax?

Perl lets you tie a behaviour to a particular syntax, because people relate syntax with behaviour. Using the right combination, this makes things easier because you raise the level of abstraction and reuse a familiar conceptual model including its syntax. It makes it appear that there is a special builtin type that eg. knows that you want the lines of a file as an array and lets you work with that array (conceptually and notationaly) just like any other array. How cool is that? :-)

tied is the way to get past tie's illusion and the only thing you'll find is that you were tricked, but you should have known that all along. That you need tied to remind you just goes to show how effective tie can be in creating the illusion in the first place.
