# Unsetting References

When you unset the reference, you just break the binding between variable name and variable content. This does not mean that variable content will be destroyed. For example:

    $a = 1;
    $b =& $a;
    unset ($a);

won't unset `$b`, just `$a`.

Again, it might be useful to think about this as analogous to Unix unlink call.
