Returns the initialization form of slot. This can be any form. This is the defaulted value of the :initform initialization argument that was associated with the slot definition metaobject during initialization. When slot has no initialization form, the value returned is unspecified (however, slot-definition-initfunction is guaranteed to return nil).

This generic function can be called by the user or the implementation.

An error is signaled if the argument slot is not a slot definition metaobject. An error is also signaled if the slot definition metaobject has not been initialized.
