    /**
     * Make an iterator that returns the values from this iterable
     * sorted by $strategy
     *
     * When determining the order of two entries the $strategy is called
     * twice, once for each value, and the results are used to determine
     * the order.  $strategy is called with two parameters: the value and
     * the key of the iterable as the first and second parameter, respectively.
     *
     * When $reverse is true the order of the results are reversed.
     *
     * The sorted() function is guaranteed to be stable.  A sort is stable
     * if it guarantees not to change the relative order of elements that
     * compare equal.  this is helpful for sorting in multiple passes (for
     * example, sort by department, then by salary grade).  This also
     * holds up when $reverse is true.
     *
     * > $list = [['type'=>'B', 'title'=>'second'], ['type'=>'C', 'title'=>'third'], ['type'=>'A', 'title'=>'first']]
     * > iter\iterable($list)->sorted('type')
     * ['type'=>'A', 'title'=>'first'] ['type'=>'B', 'title'=>'second']] ['type'=>'C', 'title'=>'third']
