Compiling extensions to python from another language also provide opportunities to fuse two or more operations, resulting in speed up even for cases where fast but independent implementation of operations are already available in python. And may be really worth it if that functionality is needed frequently. I have been writing python extensions[0] using Nim language for a while now and it has been a very smooth experience every time.
