## Notes ## Notes
You can check compiler inlining decisions using `go run -gcflags "-m" .`. Some functions look a bit weird compared to similar ones You can check compiler inlining decisions using `go run -gcflags "-m" .`. Some functions look a bit weird compared to similar ones
because we are trying to reduce function complexity so the compiler inlines. because we are trying to reduce function complexity so the compiler inlines.
