* Gets the current content of a slot, if any.

* The name of the slot.
* @param boolean $default_slot_name
* Optional. If the slot named in $slot_name returns null,
* the handler corresponding to the default slot will be called,
* passing it the requested slot's name in the 'slot_name' parameter,
* and its value will be returned instead.
* Note: this does not fill the slot named $default_slot_name!
* That is to say, the computed value is not saved, so that
* the slot's handler is called again if it is ever consulted again.
* @param string $prefix
* Optional. Sets a prefix for the HTML ids of all the elements in the slot.
