I noticed during testing that within a callbackFlow { ... } if we throw a plain Exception this halts the VM immediately, and is not caught as an in-Flow `.catch`able error, while throwing a RuntimeException is `.catch`able.
While this isn't so surprising given the conventional relationship between Exception and RuntimeException, I can't find this documented in respect to Flows - should it be? Is it?

on playground, the ordering of send vs catch seems non-deterministic but catch always seems to work: https://pl.kotl.in/kihB7LrBS

Thanks @ephemient, nice use of playground too 👍

The difference must in our code, this helps.
