Indeed, lesson learned.  In my slim defense, seeing in help(keyword):

DATA
    __all__ = ['iskeyword', 'kwlist']
    keyword = 'yield'
    kwdict = {'and': 1, 'assert': 1, 'break': 1, 'class': 1, 'continue': 1...
    kwlist = ['and', 'assert', 'break', 'class', 'continue', 'def', 'del',...

I (mistakenly) assumed kwdict was safe for usage.  Relying on help(), while I
acknowledge may have been mistaken, is not IMHO a completely farfetched error. 
Oh well, live and learn :)

Thanks to all for the clarifications.  I'll be far more careful in the future
with my usage of stuff from the stdlib.

Best,
