"""Jython print_function doctest example.

Under Python 2 by default, print(1, 2, 3) would be seen as
a print statement given a tuple, and give:

   (1, 2, 3)

Under Python 3 by default, it would be seen as a call to the
print function and give:

   1 2 3

Let's try it in a doctest where we've explicitly asked for a
print function via the future import.

   >>> print(1, 2, 3)
   1 2 3
