> Yes, but if it ends up creating any ephemeral objects in the process of determining those returned objects, then the allocation sequence is still not homogeneous.
Yes! People might do `map` transformations, but it's very common to do other stuff at the same time. Any other allocations during that transformation would ruin cache hit rate.
> At the same time, the callsite for any given `.new()` invocation will almost always be creating an instance of the exact same class. The target expression is nearly always just a constant name. That makes it a prime candidate for good inline caching at those callsites.

Yes again!
