> {{GString}} will run {{toString()}} whenever its literal string is needed,
> e.g. methods like {{equals}}, {{hashCode}} are called, but unfortunately its
> literal string will be re-constructed for each time and the process costs
> quite a little of time.
> So I propose to check whether {{GString}} values are all of immutable type,
> e.g. primitive types and their boxed type, {{String}}, etc. If yes, use the
> cached string literal, otherwise re-construct the literal string.
