1.3.3 Printing Notation
-----------------------
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 ‘⊣’. The value that is returned by evaluating the expression is
displayed with ‘⇒’ (‘1’ in the next example) and follows on a separate
line.
printf ("foo %s\n", "bar")
⊣ foo bar
⇒ 1
