> `InvokeLike.invoke` uses `map` to evaluate arguments:
> {code:java}
> val args = arguments.map(e => e.eval(input).asInstanceOf[Object])
> if (needNullCheck && args.exists(_ == null)) {
>   // return null if one of arguments is null
>   null
> } else { 
> {code}
> which seems pretty expensive if the method itself is trivial. We can change it to a plain for-loop.
