Because module A can modify module B's namespace at runtime the compiler can't tell whether an access to len() will get the builtin or a shadow version. For the above to be true the semantics of modules will have to be changed.

Yes, as I outlined earlier this week: we should disallow modifications of this kind if the text of the modified module doesn't explicitly allow it. See:

http://mail.python.org/pipermail/python-dev/2004-April/044475.html

for details.
