Thanks for the reply.

I did not know it was already discussed.
The conclusion of the thread looks reasonable.

My previous attempt which ended with "Raymond Hettinger: I don't think it is 
worth it."

Most string comparisons are comparisons of strings of less than 20 characters.

[issue30093] Unicode eq operation with hash.

[Dong-hee Na]

New submission from Dong-hee Na:

If the Unicode compare operation is done by comparing the hashes, it is likely 
to be efficient because memory comparison is not necessary.

If this idea is approved I could upload my PR right now. :-)
(I already checked local unit test is passed.)
