See my recent checkin on HEAD for fixing def foo((x)):
in the AST compiler. I had to modify test_inspect
because the above signature should not do tuple
unpacking. inspect thinkgs it does though.

That's a bit odd. Following defs:

def bar((x)): pass
def foo(x): pass

In 2.4:

>>> dis.dis(bar)
  1           0 LOAD_FAST                0 (.0)
              3 STORE_FAST               1 (x)
              6 LOAD_CONST               0 (None)
              9 RETURN_VALUE
>>> dis.dis(foo)
  1           0 LOAD_CONST               0 (None)
              3 RETURN_VALUE

In 2.5:

>>> dis.dis(bar)
  1           0 LOAD_CONST               0 (None)
              3 RETURN_VALUE
>>> dis.dis(foo)
  1           0 LOAD_CONST               0 (None)
              3 RETURN_VALUE

This at least explains why test_inspect didn't fail for 2.5
after you had fixed the bug and modified the test.

Can this bug be closed? It seems that the only problem
was test_inspect relying on the old behavior.

Yes, it seems so.
