This phrase normally parses as "Python does not consider a class  
definition as a separate namespace.  In contrast, Python does consider a  
function definition as a separate namespace."  If you meant "Python does  
not consider a class definition as a separate namespace *in the same way*  
that it does for function definitions," saying so would make life easier  
for the fairly large number of readers of this newsgroup whose first  
language isn't English.

Language abuse: it's not just Python.  A donation of just $5 will keep a  
programmer in prepositions for a month.  $50 will supply enough articles  
to keep a small company understandable for over a year.  With your  
generous help, we can beat this scourge!

Ahem.

Normal service will now be resumed.
