Yes probably just for reasonable performance, and I don't actually need to use Python's rich object model. Mostly, I just use Python to call C++ for easier interface (and C++ is for performance). And before Python 3 since there is no type annotation, refactoring is quite annoying. I'm not an PL expert, so I would like to ref a previous discuss in discourse, which is more detailed https://discourse.julialang.org/t/julia-motivation-why-werent-numpy-scipy-numba-good-enough/2236/5 https://discourse.julialang.org/t/julia-motivation-why-weren... I was just trying to say that if you want to develop something with reasonable performance, elegant interface in a short time. Probably under this situation, Julia is more suitable.
