My previous post talked about the compiler that Chris and I built. This post is about some optimization tricks that we’ve added since.

Pretty much all of these tricks are standard operating procedure for language runtimes (OCaml, MicroPython, Objective-C, Skybison, etc). We didn’t invent them.

They’re also somewhat limited in scope; the goal was to be able to add as much as possible to the baseline compiler without making it or the runtime notably more complicated. A fully-featured optimizing compiler is coming soon™ but not ready yet.
