Re: jsinterop export method that returns Optional

Thanks guys, I've gone with Jens' suggestion in the end. I don't need the full Function et al stuff, just isPresent and get for my use case. So I was able to just export only those methods.

Clearly GWT is emulating Optional under the hood for internal code. Is it possible to export the Optional class as well?

At the moment it compiles, but gives me a warning:

[unusable-by-js] Return type of 'Optional MyClass.myMethod(String)' is not usable by but exposed to JavaScript.
