Personally, I'd be fine with leaving at least the embedded attribute 
access out of the initial implementation of the PEP. I'd even be OK with 
leaving out the embedded item access, but if we leave it in "vars(obj)" 
and the embedded item access would still provide a shorthand notation 
for access to instance variable attributes in a format string.

So +1 for leaving out embedded attribute access from the initial 
implementation of PEP 3101, and -0 for leaving out the embedded item access.

Cheers,
Nick.
