Returns a function for creating readable streams from circular array-like objects.

@param {Options} [options] - stream options
@param {boolean} [options.objectMode=false] - specifies whether a stream should operate in object mode
@param {(string|null)} [options.encoding=null] - specifies how `Buffer` objects should be decoded to `strings`
@param {NonNegativeNumber} [options.highWaterMark] - specifies the maximum number of bytes to store in an internal buffer before pausing streaming
@param {string} [options.sep='\n'] - separator used to join streamed data
@param {Function} [options.serialize] - custom serialization function
@param {integer} [options.iter=1e308] - number of iterations
@param {integer} [options.dir=1] - iteration direction
@throws {TypeError} options argument must be an object
@returns {Function} stream factory
