A handful of smaller improvements. Some of these are micro-optimizations, but a few had some measurable impact. I don't think there is much low-hanging fruit that I can use these same tricks on as far as I can tell, but here are the general flavors of these changes:
Omit
+ intersection to "replace" a particular property on a type instead of mapping each property directly.None of these seem to be silver bullets, and required actually benchmarking the changes to detect if they made things worse or better. Still not sure if I have a good intuition yet.
