15.1.8 Inheritance Structure of Metaobject Classes

funcallable-standard-object is implemented as defined in AMOP, except that its class precedence list has direct superclasses

(function standard-object)

rather than

(standard-object function)

so that LispWorks is compliant with the ANSI Common Lisp rules.

For details, see the LispWorks Reference Manual page for funcallable-standard-object .
