<p>Many of the examples in this manual print text when they are
evaluated. In this manual the printed text resulting from an example
is indicated by ‘<samp>-|</samp>’. The value that is returned by
evaluating the expression is displayed with ‘<samp>⇒</samp>’
(<code>1</code> in the next example) and follows on a separate line.
