Possible optimization: hashing

[LifeIsStrange]

Leverage hashing for detecting change much much faster than a deep comparison?
And microdiff would have optionally a backing buffer/cache of previous object hashes?

[denis-bel]

What do you propose to hash? If I understand you, you want to hash objects and compare hashes, and only if hashes are different, do comparison?

I think the user should do this themselves because this would increase code size, and for many things, a lack of changes is unlikely enough that the disadvantages outweigh the advantages.
