Hello,
I just watched GopherCon 2017: Aditya Mukerjee - Translating Go to Other (Human) Languages, and Back Again, which is about this project if I'm not mistaken.
I also just launched the wiki research project Internationalisation of Programming Languages.
This project is very interesting, but not yet completely what I would be looking for, as it focus on Bengali. I would far more interested by it if it adopted an internationalisation approach, with Bengali as one of its proposed localisation. If you are interested in directing the project in that direction, I would be happy to help you. Just let me know your feeling about that, and if it is positive, how you think I might help best as a first step.
By the way, did you know that koro means hearth in Esperanto? ❤️
Cheers
