You said it yourself:  "It's not hard to come up with ...".  That's not what "real life" means.  Here:

>>> len(set(hash(1 << i) for i in range(100_000)))
61

Wow!  Only 61 hash codes across 100 thousand distinct integers?!

Yup - and I don't care.  I contrived the case, just like you apparently contrived yours.
