I read through Arraymancer readme and the rationale and got very mixed feelings about the project and its purpose. It's everything and nothing at the same time. NumPy like syntax and functionality, sklearn algorithms and look, deep learning too, here is and example and some screens which we borrowed from Scipy. Seriously? Sorry if that might be too judgemental but it sounds and looks amateurish. And I thought of benchmarking it against D mir... Also, the name... And this is what I feel about Nim in general, rushed and undercooked.
