It's because "use strict" is *strict*, and doesn't like this line:

($even_iter,$odd_iter) = even_odd_print_gen(10);

As it says, it doesn't like the fact that these two global variables aren't
explicitly put in package main.  If you write it

my ($even_iter,$odd_iter) = even_odd_print_gen(10);

then you uncover the other problem that's left as an exercise (Hint: it's a
missing #).  Fix them, and the script works as advertised.
