[issue4647] Builtin parser module fails to parse relative imports

[Kay Schluehr]

New submission from Kay Schluehr :

I've added the following test method:

test_parser.py 
--
class RoundtripLegalSyntaxTestCase(unittest.TestCase):

def test_relative_import_statement(self):
self.check_suite("from . import sys")

The test fails raising the message:

Traceback (most recent call last):
  File "test_parser.py", line 182, in test_relative_import_statement
self.check_suite("from . import sys")
  File "test_parser.py", line 29, in check_suite
self.roundtrip(parser.suite, s)
  File "test_parser.py", line 20, in roundtrip
self.fail("could not roundtrip %r: %s" % (s, why))
AssertionError: could not roundtrip 'from . import sys': Expected node
type 1, got 23.


Apparently the parser expects a NAME token and gets a DOT token.

This behaviour affects Python 2.5 and Python 2.6. Unchecked for Python 3.0.
