make-instance

(make-instance 'class-name :initarg value ...)

Creates an instance of a defclass class. Slots are supplied by their :initarg keywords (defaulting to the slot-name keyword); an unsupplied slot takes its :initform (or nil). The class name must be a literal quoted symbol naming a class already defined by defclass — there is no runtime class table, so a computed class name is an error. Like format, make-instance is a macro with no function value, so #'make-instance is unsupported.
