  @method some(<f>, [scope])
  @returns Boolean
  @short Returns true if any element in the array matches <f>.
  @extra [scope] is the %this% object. %any% is provided as an alias. In addition to providing this method for browsers that don't support it natively, this method also implements @array_matching.
  @example
  
  +   ['a','b','c'].some(function(n) {
  return n == 'a';
  });
  +   ['a','b','c'].some(function(n) {
  return n == 'd';
  });
  ['a','b','c'].some('a')   -> true
  [{a:2},{b:5}].some({a:2}) -> true
