Thanks for the explanation.  I realize that I should not have used the
s-word. :-)  In fact I only wanted a module level constant utc = UTC()
and did not care much about other UTC class instances and whether any
are permitted or easy to create.

Well, the datetime module is not exactly the place you want to start
if you want to lead anyone to best Python practices. :-) (Just think
of datetime subclassing from date!)

This is exactly my preferred solution.
