/**
 * Returns true if at least some of the elements of the input iterable are

 *
 * @example
 * some( repeat( false ) , 10 ) ; // loops forever
 *
 * @example
 * some( nrepeat( true , 10 ) , 11 ) ; // returns false
 *
 * @param {Iterable} iterable - The input iterable.
 * @param {Number} n - The number of elements that should be truthy.
 * @returns {Boolean} Returns <code>true</code> if at least <code>n</code>
