- inert(task) returns a plain task descriptor without PromiseLike or AsyncIterable protocols, safe to yield from an (async) generator without triggering auto-await - map(run, items, { concurrency, signal }) dispatches an iterable or async iterable of tasks to a Runner with bounded concurrency, yielding results in completion order - Accepts mixed task types: Task<string> | Task<number> yields string | number - Supports AbortSignal for stream cancellation; moroutine auto-transfers signals passed as task args so in-flight work can observe the same abort Includes test coverage, a bounded-map example that hashes a directory tree via recursive async generator, and a README section.
