Do you see what's wrong here? ...

Python 2.5.2 (r252:60911, Jul 22 2009, 15:35:03) 
[GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> if None:
...   print x
...  print y
  File "<stdin>", line 3
    print y
          ^
IndentationError: unindent does not match any outer indentation level
>>> 

The problem is that "print y" is indented less than "print x",
meaning that the indented code block containing "print x" is over,
and yet "print y" is *not* indented the same as the "if".
