| -- Fast Signal-like class -- | |
| -- This is a Signal class that is implemented in the most performant way -- | |
| -- possible, sacrificing correctness. The event handlers will be called -- | |
| -- directly, so it is not safe to yield in them, and it is also not safe to -- | |
| -- connect new handlers in the middle of a handler (though it is still safe -- | |
| -- for a handler to specifically disconnect itself) -- | |

| -- Batched Yield-Safe Signal Implementation -- | |
| -- This is a Signal class which has effectively identical behavior to a -- | |
| -- normal RBXScriptSignal, with the only difference being a couple extra -- | |
| -- stack frames at the bottom of the stack trace when an error is thrown. -- | |
| -- This implementation caches runner coroutines, so the ability to yield in -- | |
| -- the signal handlers comes at minimal extra cost over a naive signal -- | |
| -- implementation that either always or never spawns a thread. -- | |
