+@uref{http://srfi.schemers.org/srfi/srfi-88.html, SRFI-88} provides
+@dfn{keyword objects}, which are equivalent to Guile's keywords
+(@pxref{Keywords}). SRFI-88 keywords can be entered using the
+@dfn{postfix keyword syntax}, which consists of an identifier followed
+by @code{:} (@pxref{Reader options, @code{postfix} keyword syntax}).
+SRFI-88 can be made available with:
+
+@example
+(use-modules (srfi srfi-88))
+@end example
+
+Doing so installs the right reader option for keyword syntax, using
+@code{(read-set! keywords 'postfix)}. It also provides the procedures
+described below.
+
+@deffn {Scheme Procedure} keyword? obj
+Return @code{#t} if @var{obj} is a keyword. This is the same procedure
+as the same-named built-in procedure (@pxref{Keyword Procedures,
+@code{keyword?}}).
+
+@example
+(keyword? foo:) @result{} #t
+(keyword? 'foo:) @result{} #t
+(keyword? "foo") @result{} #f
+@end example
+@end deffn
+
+@deffn {Scheme Procedure} keyword->string kw
+Return the name of @var{kw} as a string, i.e., without the trailing
+colon. The returned string may not be modified, e.g., with
+@code{string-set!}.
+
+@example
+(keyword->string foo:) @result{} "foo"
+@end example
+@end deffn
+
+@deffn {Scheme Procedure} string->keyword str
+Return the keyword object whose name is @var{str}.
+
+@example
+(keyword->string (string->keyword "a b c")) @result{} "a b c"
+@end example
+@end deffn
