Python 3.0 doesn't print the string with the carat underneath when
there is a syntax error.

>>> if x
SyntaxError: invalid syntax (<stdin>, line1)
>>> if (x=5):
SyntaxError: invalid syntax (<stdin>, line 1)

Python 2.x behavior:

>>> if (x=5): pass
  File "<stdin>", line 1
    if (x=5): pass

>>> if x
  File "<stdin>", line 1
    if x

Yup. Same if the exception comes in a file. I'll try to free up some
cycles to look into this. Thanks for the report!
