Runtime characteristics

Optimized fire paths

CuteSignal swaps the active :Fire implementation based on state:

• no listeners: no-op fire path
• one sync listener: direct callback fast path
• mixed listener sets: async listeners first, then sync listeners
• waiters present: listeners fire first, then waiting threads resume

Low-overhead listener management

• Disconnect uses swap-remove for O(1) listener removal.
• Dispatch snapshots are rebuilt on connect/disconnect to keep iteration stable.
• Disconnect functions are idempotent, and stale disconnects are ignored via generation checks.

Async runner reuse

:ConnectAsync callbacks run through a reusable coroutine runner cache. If a callback yields, additional runners are allocated as needed.

Lifecycle guarantees

After calling :Destroy():

• :Connect, :ConnectAsync, and :Wait throw "Signal is destroyed".
• :Fire, :DisconnectAll, and :Destroy become no-ops.
• :Count() returns 0, :HasConnections() returns false, and :IsDestroyed() returns true.
