/**
 * Returns the result of concatenating the given lists or strings.
 *
 * Note: R.concat expects both arguments to be of the same type, unlike
 * the native Array.prototype.concat method.
 * It will throw an error if you concat an Array with a non-Array value.
 * Dispatches to the concat method of the second argument, if present.
