Why is there no natural syntax for accessing attributes with names not being valid identifiers?

The obvious thing to do is to either raise this on python ideas, or if 
you're that confident about it raise an issue on the bug tracker with a 
patch, which would include changes to unit tests and documentation as 
well as code, get it reviewed and approved and Bob's your uncle, job 
done.  Too late for Python 3.4 of course, but no problem for 3.5.
