 * @category Collection
 * @param {Array|Iterable|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 the array
 * in parallel. 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 as soon as any
 * iteratee returns `true`, or after all the iteratee functions have finished.
 * Result will be either `true` or `false` depending on the values of the async
 * tests. Invoked with (err, result).
