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 👍
