// 1) Modify params_ref to create a copy of set_str parameters.
// This solution is not nice since we create copies and move the params_ref around.
// We would have to keep copying the strings.
// Moreover, when we use params_ref internally, the value is usually a static value.
// So, we would be paying this price for nothing.
// 2) "Copy" value by transforming it into a symbol.
// I'm using this solution for now.
