As I recall the big reason for namedtuples was things like

     sys.version_info[1]  # behind door number one is...

being much more readable as

     sys.version_info.minor

In other words, the tuple offsets are named -- hence, namedtuples.  And 
only valid identifiers will work.

So, no, it has nothing to do with 'exec', and everything to do with the 
problem namedtuple was designed to solve.
