Summary: Cannot doctest a SyntaxError

Initial Comment:
Currently, doctests cannot be used to demonstrate or
test that misconstructions produce a syntax error.  I'm
not certain, but I believe that case is trappable and
veriable.  

The following is an actual use case for one of the
tests I would like to have in test.test_genexps.py:


Verify that parenthesis are required in a statement
>>> def f(n):
...     return i*i for i in xrange(n)
...
SyntaxError: invalid syntax
