Description

There are a few more laws that we could reasonably add:

  • Constrain backpressure on finalizers. This is probably a couple laws, covering the singular cancel and the multi-cancel case
  • Find a way to write a law which shows that async finalizers are real finalizers

Probably some more stuff. This is just what's in my head right now.

Research direction

The issue names no files, tests, or entry points, and only suggests additional laws around finalizers, cancellation, backpressure, and async finalizers. Start by locating the existing law tests for these behaviors; completion would require agreed-upon laws and passing tests, but the issue does not define the expected assertions.
