I still don't understand your aversion to singletons and you did not
address any of the advantages that I listed in my previous comment. I
don't think singletons are foreign to Python: after all we write None
rather than NoneType() .
We can reach a middle ground by interning UTC instances behind the
scenes so that UTC() is UTC() will always be true. This will address
most of the issues that I raised and utc = datetime.UTC() is simple
enough to write as long as you don't have to worry about sharing utc
instance between modules.
