How many of those "class_" instances are really just substrings of 
"__class__" and "class_name" and such?  On my machine, I see a handful 
in the standard library, and _none_ in site-packages (which has only 
1709 .py files, mind you).

Actually what he posted explicitly states that "cls" is preferred. 
Following that it says that one should considering appending _ if the 
name conflicts with a keyword (and one can assume it means "for all 
keywords other than class").

As has been pointed out, klass has a fairly established tradition of 
use.  (I happen to agree with the PEP and use "cls" exclusively for such 
things, and do agree that "klass" is crude.)
