Well , I guess language design is just hard... Yet the demand exists, and it's huge no question.
Out of all of these, i still think D is the most interesting one (I like C#, I want generics ...).
I don't agree with some choices Nim made but it still look interesting. Go is way too rigid for my programming style. Yet Go set some expectations when it comes to developer experience, so it was a step in the right direction.
