I’m talking about code organization, not types. In Julia, methods are grouped together by type dispatch, mostly. There are times when code reuse comes into play where it’s helpful, but mostly it just confuses the issue and introduces ambiguity into the structure of the program in the big picture sense.

My mistake, I saw your name was xiaodai and assumed.

My point is, Julia is not suited for general software, and it’s questionable as a tool for technical computing as well.

For running simulations and models where the code can be written and never looked at again, maybe it’s okay to use. But for anything else, Python is a lot nicer, and a lot more practical to write proper software in.
