Problem Description<P>
|
|
The Character Committee Report Proposal 2.2.1 (passed 3/89) requires<P>
|
|
implementations to support and document a <A REL=DEFINITION HREF="../Body/07_ffb.htm#standard"><B>STANDARD</B></A> character subrepertoire,<P>
|
|
whose elements are the specified set of characters. This set of characters<P>
|
|
corresponds exactly to those characters which are of type <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A>.<P>
|
|
<P>
|
|
The Character Committee Report Proposal 2.4.3 (passed 6/89) states that<P>
|
|
every character repertoire name is a type specifier.<P>
|
|
<P>
|
|
Thus we have two atomic type specifiers for precisely the same thing. The<P>
|
|
type <A REL=DEFINITION HREF="../Body/07_ffb.htm#standard"><B>STANDARD</B></A> is equivelent to the type <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A>.<P>
|
|
<P>
|
|
<B>Proposal (STANDARD-REPERTOIRE-GRATUITOUS:RENAME):<P>
|
|
</B> Change the name of the <A REL=DEFINITION HREF="../Body/07_ffb.htm#standard"><B>STANDARD</B></A> character subrepertoire required by<P>
|
|
Character Proposal 2.2.1 to be <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A>.<P>
|
|
<P>
|
|
<B>Rationale:<P>
|
|
</B> This removes the duplication.<P>
|
|
<P>
|
|
<B>Current Practice:<P>
|
|
</B> Probably none.<P>
|
|
<P>
|
|
<B>Cost to Implementors:<P>
|
|
</B> Probably none.<P>
|
|
<P>
|
|
<B>Cost to Users:<P>
|
|
</B> Probably none.<P>
|
|
<P>
|
|
<B>Benefits:<P>
|
|
</B> Eliminates possible confusion when a person reading some code sees<P>
|
|
(<A REL=DEFINITION HREF="../Body/f_typep.htm#typep"><B>TYPEP</B></A> foo '<A REL=DEFINITION HREF="../Body/07_ffb.htm#standard"><B>STANDARD</B></A>)<P>
|
|
and wonders "STANDARD what? Transmission?"<P>
|
|
<P>
|
|
<B>Discussion:<P>
|
|
</B> Pitman and Barrett support this proposal (RENAME).<P>
|
|
<P>
|
|
There was initally some concern that <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A> might not be a valid<P>
|
|
repertoire name, but there are no restrictions placed on the names of<P>
|
|
repertoires in any of the proposals in the Character Committee Report<P>
|
|
dated 7/25/89. There is a footnote (#15) that constrains character<P>
|
|
scripts and labels to only use Latin capitals A-Z, hyphen, and digits<P>
|
|
0-9, which the name <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A> satisfies. Since this is a footnote,<P>
|
|
it can be argued that it has no force anyway.<P>
|
|
<P>
|
|
Unfortunately, this still doesn't remove <A REL=DEFINITION HREF="../Body/07_ffb.htm#standard"><B>STANDARD</B></A> as a defined name<P>
|
|
(i.e., exported symbol of the cl package) since it's used by CLOS for<P>
|
|
what might be argued to be an equally ungeneric purpose. There's a <P>
|
|
fair chance that somebody somewhere along the line is going to get <P>
|
|
annoyed by the inter-package sharing that occurs due to this symbol<P>
|
|
being present.<P>
|
|

Moon (9 Jan 90):<P>
|
|
<P>
|
|
I support this. I think it's only an accident of the process for<P>
|
|
amending the character committee's proposals that the duplication<P>
|
|
between <A REL=DEFINITION HREF="../Body/07_ffb.htm#standard"><B>STANDARD</B></A> and <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A> was overlooked. Given that we<P>
|
|
want to get rid of one of the two duplicate names, it's clear<P>
|
|
that <A REL=DEFINITION HREF="../Body/t_std_ch.htm#standard-char"><B>STANDARD-CHAR</B></A> is a better name.<P>
