<P>
|
|
<B>Problem description:<P>
|
|
</B><P>
|
|
<A HREF="iss359.htm">WITH-ADDED-METHODS</A> has a strange definition that is hard to understand<P>
|
|
and apparently is not what was intended by the person who originally<P>
|
|
proposed the feature. No CLOS implementation is known that supports it.<P>
|
|
<P>
|
|
This is Symbolics issue #17.<P>
|
|
<P>
|
|
<B>Proposal (WITH-ADDED-METHODS:DELETE):<P>
|
|
</B><P>
|
|
Remove <A HREF="iss359.htm">WITH-ADDED-METHODS</A> from the language and remove that symbol from<P>
|
|
the COMMON-LISP package.<P>
|
|
<P>
|
|
<B>Rationale:<P>
|
|
</B><P>
|
|
Why add something new that no one uses or wants?<P>
|
|
<P>
|
|
<B>Current practice:<P>
|
|
</B><P>
|
|
No CLOS implementation is known to support <A HREF="iss359.htm">WITH-ADDED-METHODS</A>.<P>
|
|
<P>
|
|
<B>Cost to Implementors:<P>
|
|
</B><P>
|
|
Trivial.<P>
|
|
<P>
|
|
<B>Cost to Users:<P>
|
|
</B><P>
|
|
None.<P>
|
|
<P>
|
|
<B>Cost of non-adoption:<P>
|
|
</B><P>
|
|
We would either have to get the implementors to implement it or explain<P>
|
|
why we put this thing in the language that everyone refuses to implement.<P>
|
|
<P>
|
|
<B>Performance impact:<P>
|
|
</B><P>
|
|
None.<P>
|
|
<P>
|
|
<B>Benefits:<P>
|
|
</B><P>
|
|
Smaller language.<P>
|
|
<P>
|
|
<B>Esthetics:<P>
|
|
</B><P>
|
|
Smaller language.<P>
|
|
<P>
|
|
<B>Discussion:<P>
