Summary: compiler.transformer and tuple unpacking

Initial Comment:
compiler.transformer.parse chokes on tuple unpacking
when parentheses are present.

To reproduce, try:

import compiler.transformer
compiler.transformer.parse('(a, b) = 1, 2')

... in Python 2.3 and Python 2.4.  It works in Python
2.3. In Python 2.4, it causes a SyntaxError "bad
assignment".

It works in both Python versions when omitting the
parentheses, i.e. using 'a, b = 1, 2' instead.
