Is there any advantage to deleting vars instantiated within public or private functions in a class, or are they removed from memory after the function has been invoked/run? The function below is completely arbitrary for example:

```
 ActionScript Code:
 [FONT=Courier New][LEFT][COLOR=#0000ff]private[/COLOR] [COLOR=#000000] **function** [/COLOR] someFunctionHere[COLOR=#000000]([/COLOR]_ar:[COLOR=#0000ff]Array[/COLOR][COLOR=#000000])[/COLOR]:[COLOR=#0000ff]Void[/COLOR] [COLOR=#000000]{[/COLOR]
    [COLOR=#000000] **var** [/COLOR] _swf:[COLOR=#0000ff]String[/COLOR] = _ar[COLOR=#000000][[/COLOR][COLOR=#000080]0[/COLOR][COLOR=#000000]][/COLOR];
    [COLOR=#000000] **var** [/COLOR] _nm:[COLOR=#0000ff]String[/COLOR] = _ar[COLOR=#000000][[/COLOR][COLOR=#000080]1[/COLOR][COLOR=#000000]][/COLOR];
    [COLOR=#000000] **var** [/COLOR] _num:[COLOR=#0000ff]Number[/COLOR] = [COLOR=#000080]5[/COLOR];
    
    [COLOR=#808080]*//use them here*[/COLOR]

    [COLOR=#0000ff]delete[/COLOR] _swf;
    [COLOR=#0000ff]delete[/COLOR] _nm;       
    [COLOR=#0000ff]delete[/COLOR] _num;

```
