Task.of<R,E,>(task: (signal?: AbortSignal) => Promisable<R>): Task<R, E>
Creates a Task from a sync or async function. The function receives an optional AbortSignal that is active when the task is run with a signal via withSignal or run.
Note: the error type E is unchecked and represents the expected error
shape rather than a runtime guarantee.
