Thread local, `!Send + !Sync` version of `Event` about event-listener HOT 4 CLOSED

Previously, I was working on a thread-unsafe async framework called unsend, which had thread unsafe versions of most of smol's primitives. I stopped developing because I heard that Rust was moving towards adding !Send + !Sync versions of Waker, and if they did that it would change up my model considerably.

That being said, smol is intended to be thread-safe. Barring some kind of crazy generic solution, I don't see us moving forward on this.

Do you mean this: rust-lang/libs-team#191 ?

smol is intended to be thread-safe.

If this is the case, maybe LocalExecutor shouldn't be included either?

I've released unsend version 0.1.0, with an Event structure similar to the one in this crate, but is !Sync and doesn't use any synchronization primitives.

Since we are not planning on adding an equivalent structure to EventListener, I'll close this issue now.

If this is the case, maybe LocalExecutor shouldn't be included either?

LocalExecutor is a special case I feel, because most contemporary async runtimes (even thread-safe ones) provide a LocalExecutor analogue.
