Slot: extra_slots

How a class instance handles extra data not specified in the class definition.

Note that this does not define the constraints that are placed on additional slots defined by inheriting classes.

__

Possible values:

- allowed: true - allow all additional data

_- allowed: false (or allowed: or allowed: null while range_expression is null) - _

_ forbid all additional data (default) _

- range_expression: ... - allow additional data if it matches the slot expression (see examples)
