> My final question about any tool is more personal: "Does it use C++?" because, if it does, then integrating with anything other than C++ is going to be a gigantic PITA. At this point there are plenty of fine alternatives to C++ that don't suck. If you don't have a clean, pleasant way of talking to things that only understand C library conventions, you fail and I'm moving on.

I think you've got that the wrong way around; if you can talk to things using the C library, you automatically get reusability from Java, C#, Python, various Lisps, Ruby, Rust (Go?), and almost every halfway popular language in existence.

What alternative do you know off that is more widely supported by all programming languages?
