-@subsubsection Keyword Primitives
-
-Internally, a keyword is implemented as something like a tagged symbol,
-where the tag identifies the keyword as being self-evaluating, and the
-symbol, known as the keyword's @dfn{dash symbol} has the same name as
-the keyword name but prefixed by a single dash.  For example, the
-keyword @code{#:name} has the corresponding dash symbol @code{-name}.
-
-Most keyword objects are constructed automatically by the reader when it
-reads a token beginning with @code{#:}.  However, if you need to
-construct a keyword object programmatically, you can do so by calling
-@code{make-keyword-from-dash-symbol} with the corresponding dash symbol
-(as the reader does).  The dash symbol for a keyword object can be
-retrieved using the @code{keyword-dash-symbol} procedure.
