@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
