Julia is better than Python for a lot of things - basically when you can't vectorise your algorithm and don't feel like writing C++.

Python has numba, which is equally backed by LLVM. What makes Julia interesting compared to Python IMO is its macro system much more than its performance benefits.

Although unequally inconvenient when working with user-defined types. Possible now (wasn't always) but not seamless. Are there examples of libraries that depend on Numba?
