Javascript local variable declare

Question

Basically this is a question how to access local scope handler. I trying to achieve something similar for global variable definition like:

window['newObject'] = "some string";
alert(newObject);

but for local scope. Right now only solution I have is using evals:

eval("var newObject='some string'");

But this is really ugly solution... The best one would be like using some reference to local scope like in a window[] solution, but I never heard of any reference to local scope... Any ideas ?

Example goes here:

function x(arg)
{
   localScope[arg.name]=arg.value;
   alert(sex);
}

x({name:"sex", value:"Male"});

Okey I found related question that is talking about what I need...

How can I access local scope dynamically in javascript?

I just remember that in ECMA 262 is only one way to add dynamically local variables to scope using "with" statement (and eval of course), here are solution:

var x=function(obj)
{

    with(obj) 
    {
       alert(someObj);
    }
 }
 alert(typeof someObj);


 x ( {someObj:"yea"}) ;

 alert(typeof someObj);
