You can, of course, reduce this to;


interface Processor {
 
    ...
    
    static <T> StringTemplate.Processor<T, RuntimeException> of(Function<StringTemplate, T> function) {
        return function::apply;
    }
    
    ...

}


since String is just a type. This proposal has merit and worth some thought. -2 interfaces, +1 method.
