All three patches look different to me.

There's still interest, at least from me :)

In my opinion we should have the documented behavior (integer or identifier as field_name), AND braces should be disallowed inside the format string, with the exception of one level of nesting in the format_spec part.

This should probably be taken to python-dev once more, as the previous discussion didn't reach consesus, except that the current approach is bad and something needs to be done.
