Python 3, metaclasses and __prepare__ (aka PEP 3115).

The performance of the local function namespace is critical to Python's
speed characteristics, so slowing it down would not be appreciated (and
odicts definitely *are* slower than regular dicts due to the extra
checks involved).

The performance of class namespaces during definition is much less
critical however, and OrderedDict was added in part so that people could
easily return it from __prepare__ methods without having to write one
