Message247423
I think this is a bug. This is not a normal case of subclassing as the interpreter calls the C API PyDict_XXX() in many cases where a dictionary subclass is passed in.
For example:
class C: pass
c = C()
# Liskov substitution principle says this is OK.
c.__dict__ = OrderedDict()
c.a = 1
All access to the ordered dict is via the dict.__setitem__ method.
I think this should be documented. |
