emitter

Based on path.Match, allowing flexible event routing with patterns like '*', making it easy to subscribe to multiple events at once, as shown in the wildcard examples.

Enables event interception, modification, and skipping via middlewares, providing fine-grained control over event flow, demonstrated in the middleware section with flag setting.

Leverages Go's channel semantics to discard events by closing channels, ideal for timeout-based workflows, as detailed in the cancellation example.

Allows per-listener or per-topic choice between synchronous and asynchronous emission using flags, optimizing for different concurrency needs without locking.

Provides shallow casting of event arguments to int, string, float64, or bool with optional defaults, simplifying argument handling without manual assertions.
