Look at it this way: A classic enumeration has no use-case for
equal-but-distinct; this thread doesn't disagree with that, because
this thread is not about classic enumerations. In the same way,
integers don't have use-cases for equal-but-distinct either, but in
practice, you can distinguish between exact literals and the results
of computation:

rosuav at sikorsky:~$ cat unique_numbers.py
x = 100000
y = 100000
z = 99999+1
print(x is y, x is z, y is z)
rosuav at sikorsky:~$ python3 unique_numbers.py
True False False

This is still not good code, though. If you really need to distinguish
those, your code is majorly fragile.
