=head1 DESCRIPTION
This exception is thrown on incorrect usage of an instance of a sub-class. An
instance of this exception has the following attributes, which can be accessed
via $e->get_$attrib():
=head1 ATTRIBUTES
=over 4
=item caller
Returns an ARRAY reference containing the caller (as returned by the built-in
function in ARRAY context) that triggers the exception. Note: for a CODE-based
class, this is always the caller when the instance is created.
=item code
The error code, which can be one of the following:
=over 4
=item $e->CODE_TYPE
Attempt to set the value of an attribute to an incorrect type.
=back
=item key
The key of the attribute that triggers this exception.
=item type
The expected data type (for an attempt to set the value of an attribute to an
incorrect type).
=item value
The value of the attribute that triggers this exception.
=back
