> I need something that […] has interoperability with decades worth of C, C++ and Fortran code. Assuming you meant more than having a good FFI… When I judge the suitability of a language for a task in the abstract, I systematically ignore 2 very important factors: legacy code, and skill availability. I do as if everyone know every language, and we start from a mostly blank slate. If I didn't ignore those factors, I wouldn't be judging the languages, I would be judging whole ecosystems, introducing a huge status-quo bias in the process. --- The C+ you look for is probably possible. I bet it could be implemented a la CFront.
