A <A REL=DEFINITION HREF="26_glo_c.htm#correctable"><I>correctable</I></A> error is signaled if the <I>package-name</I> or any of the <I>nicknames</I> is already the <A REL=DEFINITION HREF="26_glo_n.htm#name"><I>name</I></A> or <A REL=DEFINITION HREF="26_glo_n.htm#nickname"><I>nickname</I></A> of an existing <A REL=DEFINITION HREF="26_glo_p.htm#package"><I>package</I></A>. <P>

<P>

In situations where the <A REL=DEFINITION HREF="26_glo_p.htm#package"><I>packages</I></A> to be used contain symbols which would conflict, it is necessary to first create the package with <TT>:use '()</TT>, then to use <A REL=DEFINITION HREF="f_shadow.htm#shadow"><B>shadow</B></A> or <A REL=DEFINITION HREF="f_shdw_i.htm#shadowing-import"><B>shadowing-import</B></A> to address the conflicts, and then after that to use <A REL=DEFINITION HREF="f_use_pk.htm#use-package"><B>use-package</B></A> once the conflicts have been addressed. <P>
|
||
|
|
When packages are being created as part of the static definition of a program rather than dynamically by the program, it is generally considered more stylistically appropriate to use <A REL=DEFINITION HREF="m_defpkg.htm#defpackage"><B>defpackage</B></A> rather than <A REL=DEFINITION HREF="#make-package"><B>make-package</B></A>. <P>
