Summary: Inconsistent Exceptions for Readonly Attributes
Initial Comment:
Attempting assignment to a readonly attribute raises an Attribute error for
pure Python attributes but raises a TypeError for C readonly attributes. I
think the AttributeError is the correct exception.
>>> class A(object):
... _x = []
...
... @property
... def x(self):
... return self._x
...
>>> a = A()
>>> a.x = None
Traceback (most recent call last):
a.x = None
AttributeError: can't set attribute
>>> def f():
... yield None
>>> g = f()
>>> g.gi_frame = None
Traceback (most recent call last):
g.gi_frame = None
TypeError: readonly attribute

I think this has something peculiar to frames, for instance:
Python 2.5 (r25:51908, Sep 25 2006, 17:50:07)
[GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> f = 'asdf'
>>> f.strip = 42
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'str' object attribute 'strip' is read-only
>>>
