Cumulatively tests whether at least one element in a provided array passes a test implemented by a predicate function.

@private
@param {Collection} x - input array
@param {Collection} y - output array
@param {integer} stride - output array stride
@param {NonNegativeInteger} offset - output array offset
@param {Function} predicate - test function
@param {*} thisArg - execution context
@returns {Collection} output array

@example
function isPositive( v ) {
    return v > 0;
}

var x = [ false, false, false, true, false  ];
var y = [ false, null, false, null, false, null, false, null, false, null ];

var out = indexed( x, y, 2, 0, isPositive );
// returns [ false, null, false, null, false, null, true, null, true, null ]
