   -- Procedures that may construct complex numbers from non-complex
     arguments may signal an error or return an incorrect value
     (for example, \texttt{(sqrt -1)} should \emph{not} be \texttt{+nan.0}).
-\item Reader does not recognize \texttt{\#!r6rs} syntax.  It should
-be modified to accept both \texttt{\#!r6rs} and \texttt{\#!ikarus}
-so that Ikarus-specific reader features (gensym syntax, record
-syntax, shared graphs, fasl objects, etc.) can be enabled/disabled as needed.
 \item The procedure \texttt{equal?}\ may not terminate on
 \texttt{equal?}\ infinite (circular) input.
 \item Representation of I/O ports is missing a transcoder field.
+\item \texttt{number->string} does not accept the third argument
+(precision).  Similarly, \texttt{string->number} and the reader do
+not recognize the \texttt{|p} notation.
