declare variables in for loop

[digitalecartoon]

This works and traces '2' five times:

for (var i = 0; i < 5; i++)
{
var d:int = 2;
trace(d);
}

I sort of understand why this doesn't:

var d:int = 2;
trace(d);
var d:int = 2;
trace(d);
var d:int = 2;
trace(d);
var d:int = 2;
trace(d);
var d:int = 2;
trace(d);

Since I get the next error:

1151: A conflict exists with definition d in namespace internal

cause I declare the same variable five times.

The thing I don't understand is why it does work in the for-loop, since in principle I'm doing the same thing there. Why isn't it a problem for actionscript when I let the same variable be declared over and over again when I use a for-loop?

I personally create a map and create dynamic variables or push all values into an array like this

var0="value1";
var1="value2";
arr0:Array=[var0,var1];
for(var i:int=0;i<2;i++){
trace(arr0[i]);
}
ouput: value0 , value1

or
map0:Object ={};
for(var i:int=0;i<2;i++){
map0['var'+i]="value"+i.toString();
trace(map0['var'+i]);
}

ouput: value0 , value1
