> It's amazing to realize that writing down the first thing that comes to your head is usually like 80% as fast as a good, performant implementation. (As someone who has done a decent amount of work in performance engineering for embedded platforms, I really enjoy squeezing out the last drop of performance from most programs, but doing this for every single first-pass at a program, like in Python, is rather annoying if this is what is needed to get a usable implementation.)
Yes, Julia is not necessarily faster than a good C implementation (that doesn't leak, etc), but, like Python, what would be a 300-line C implementation, where one has to somewhat carefully manage typing and the abstraction is really rather complicated for something that is mathematically simple, we can usually write 20 lines of very performant Julia that is 95% as fast.
Attempting to do something relatively similar in Python is often slow enough that giving a practical implementation essentially needs to be coded in C and interfaced with Python, where we return (again!) back to the same problem we had before: writing a 300+ line C file for something that should be rather simple, mathematically speaking.
