14.15.2 @result{} (⇒): Indicating Evaluation

Use the @result{} command to indicate the result of evaluating an expression.

The @result{} command is displayed as ‘⇒’ in Info and HTML and as a true double stemmed arrow in the printed output.

Thus, the following,

(cdr '(1 2 3))
    ⇒ (2 3)

may be read as “(cdr '(1 2 3)) evaluates to (2 3)”.
