Better to have searched the python-ideas mail list archive.

Because it doesn't work in general. There are strings that can be used
as an index, but not as an attribute. There are existing attributes
that you have to avoid, etc.

The only way this really works in practice is if you start with a
fixed set of names you want to access, in which case
collections.namedtuple will probably do the job.
