I can code a "proof of concept" if you think this is a good idea.

I'm willing to test it in real application if you make an implementation. I think it is necessary to check the usability of this kind of library directly in practice instead of pondering based on assumptions. It's hard to figure out the side effects or using this tool. (at least to me) Hello,

I gave a try at the implementation of the expected_or_error class. I used the boost layout to package the implementation, you can download it here : http://www.hyc.io/boost/expected.zip Finally, feel free to explore the documentation I wrote http://www.hyc.io/boost/index.html

Please, do not hesitate to give me advices and critics to improve this library and my future proposal.

Hi, glad to see you are exploring the different alternatives. This is really a good starting point. See attached my draft (not tested) of expected which is based on Alexandrescu class but adapted to boost notation and making it portable to c++98 compilers. In addition I added some additional helper functions. Now it is time to make a concrete proposal for you candidature. Best, Vicente
