<P><A NAME="generalized_boolean"><B>generalized boolean</B></A> <I>n.</I> an <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>object</I></A> used as a truth value, where the symbol <A REL=DEFINITION HREF="a_nil.htm#nil"><B>nil</B></A> represents <A REL=DEFINITION HREF="26_glo_f.htm#false"><I>false</I></A> and all other <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>objects</I></A> represent <A REL=DEFINITION HREF="26_glo_t.htm#true"><I>true</I></A>.

<P><A NAME="generalized_instance"><B>generalized instance</B></A> <I>n.</I> (of a <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A>) an <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>object</I></A> the <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A> of which is either that <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A> itself, or some subclass of that <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A>. (Because of the correspondence between types and classes, the term ``generalized instance of X'' implies ``object of type X'' and in cases where X is a <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A> (or <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A> <A REL=DEFINITION HREF="26_glo_n.htm#name"><I>name</I></A>) the reverse is also true. The former terminology emphasizes the view of X as a <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A> while the latter emphasizes the view of X as a <A REL=DEFINITION HREF="26_glo_t.htm#type_specifier"><I>type specifier</I></A>.) <P>
