5.1.2.7 Macro Forms as Places</H2> <P>

A <A REL=DEFINITION HREF="26_glo_m.htm#macro_form"><I>macro form</I></A> can be used as a <A REL=DEFINITION HREF="26_glo_p.htm#place"><I>place</I></A>, in which case Common Lisp expands the <A REL=DEFINITION HREF="26_glo_m.htm#macro_form"><I>macro form</I></A> as if by <A REL=DEFINITION HREF="f_mexp_.htm#macroexpand-1"><B>macroexpand-1</B></A> and then uses the <A REL=DEFINITION HREF="26_glo_m.htm#macro_expansion"><I>macro expansion</I></A> in place of the original <A REL=DEFINITION HREF="26_glo_p.htm#place"><I>place</I></A>. Such <A REL=DEFINITION HREF="26_glo_m.htm#macro_expansion"><I>macro expansion</I></A> is attempted only after exhausting all other possibilities other than expanding into a call to a function named <TT>(setf </TT><I>reader</I><TT>)</TT>. <P>
