Deprecated language features are not expected to appear in future \clisp\
standards, but are required to be implemented for conformance with this
standard; \seesection\ReqLangFeatures.

\term{Conforming programs} can use deprecated features;
however, it is considered good programming style to avoid them.
It is permissible for the compiler to produce \term{style warnings} 
about the use of such features at compile time, 
but there should be no such warnings at program execution time.

\beginsubsection{Deprecated Reader Syntax}

\issue{STRUCTURE-READ-PRINT-SYNTAX:KEYWORDS}
The \f{\#S} \term{reader macro} forces keyword names into \thepackage{keyword};
\seesection\SharpsignS.
This feature is deprecated;
in the future, keyword names will be taken in the package they are read in,
so \term{symbols} that are actually in \thepackage{keyword}
should be used if that is what is desired.
