* @category Collection
* @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
* @param {number} limit - The maximum number of async operations at a time.
* @param {Function} iteratee - A truth test to apply to each item in `coll`.
* The `iteratee` is passed a `callback(err, truthValue)`, which must be called
* with a boolean argument once it has completed. Invoked with (item, callback).
* @param {Function} [callback] - A callback which is called after all the
* `iteratee` functions have finished. Invoked with (err, results).
* @returns {Promise} a promise, if no callback provided
