To answer the original question, you need a boost license to get something into Phobos. I am not a lawyer, but I *believe* the boost license would satisfy the requirements of the MIT license. So I think you could just use it. But I’m not 100% sure.

I’m pretty sure the MIT license has more restrictions than the Boost licenses. That would mean you can add Boost licensed code to a MIT licensed project but not the other way around, but I’m not a lawyer.
