- This magic is invoked when a container variable is reset, i.e. when
- an array or a hash is emptied. Please note that this is different
- from undefining the variable, even though the magic is called when
- the clearing is a result of the undefine (e.g. for an array, but
- actually a bug prevent it to work before perl 5.9.5 - see the
- history).
