Great write up! I've made the same mistake of having too many subclassed entities, and realising my queries getting slower because my indexes were not being used. I think Apple should mention this caveat in their official documentation. I'm sure many folks have been bitten by this issue.

Great job @yasoob! What's even more amazing, even thought not directly relevant, is that the author is still in high school.

My initial response was "link bait!"

I wonder what's the primary reason for their "Mu" compiler adopting a "strict-ish" evaluation strategy.
