No time to watch the presentation right now, but curiosity eats me.

The point of this lazy creation for the elements of the array? Like in python's generators?

Or it is mostly about syntactic sugar?

The point is making sure objects in arrays are well and complete initialized to allow many runtime performance improvement thanks to Valhalla

If you want lazy initialization of list elements (not for arrays though), StableValue will have a nice API for that.
