CLEARING METHODS/ATTRIBUTES
We have so far seen many ways to add methods, attributes and accessors to a quick object. But you can also clear them! This is particularly useful in strict objects where they will not autovivify back into existance.
One again there are 2 ways to clear an attribute or method. The original way using the qclear
method, and the new way using the control object.
# Remove the foo() attribute and any associated value/method
$obj->foo( qclear() );
# Remove a whole list of attributes
$control->clear( qw/foo bar baz/ );
