request: expose serialize postData

[postite]

i had the need for modifying the values of a form in a pushstate.prevent.

would you expose the serializing postdata function to make it easier ?

something like that ?:

 public function serializeStatePostData(state:Dynamic):Dynamic {
var buf:StringBuf=new StringBuf();
for (a in Reflect.fields(state)){
    var p:String=Reflect.field(state,a);
    var _a=a+"="+p.urlEncode();
    buf.add(_a+"&");
}

Reflect.setField(state,"__postData",buf.toString());
return state;

}

perhaps i'm not doing it right but i don't get why we couldn't do it by default.
thx
