Interesting how we can have such vastly different experiences. When Julia makes a copy is pretty straightforward and natural IMHO. I would have been curious to see an example of the code you used where a copy was made without you knowing. I started with Python, but I find Julia better is almost every single way I can think of. Like even if Julia was slower than Python I would have picked it because I find it so much nicer to use. I wrote an article here about some of the observations I had about using Python after coming back to it from Julia: https://medium.com/@Jernfrost/python-vs-julia-observations-e61ee667fa95 https://medium.com/@Jernfrost/python-vs-julia-observations-e... There are some exchanges further down. Would have been interesting to hear your feedback on some of those things.
