  vmath is a library for vector math with support for 2d and 3d vectors. However, based on your needs, you could also build your own vector type.

  I haven’t programmed in Python a lot for years. Though I still somewhat follow the new features and versions and wow it surprises me how often modern Python misses an elegant solution that could simplify the ecosystem in favor of bespoke new syntax and new ways to do more incompatible OO.

  Interestingly I’ve actually been using _more_ duck-typing style programming in Nim as it’s become my daily driver.

  It’s kinda funny since Nim is a statically typed language you think it’d be hard yet its so seamless to use compile time checks that it’s easy to think of it as runtime duck-typing. You can add overloaded types to a function like `proc foo(arg1: int | string, arg2: float)` and then use the `with` expression to change behavior in parts of the function handling the specifics for the types. It’s really power way to handle polymorphism and things like visitor patterns without a bunch of OO infrastructure. I take it the Python type annotations aren’t embracing that overloaded type setup?

  You can even trivially use duck typing with type declarations https://nim-lang.org/docs/manual.html#generics-is-operator There’s another pattern I’ve taken to of just declaring getter/setters for things like “X” and “Y”, except just from a generic array. I mean “X” is just a convention for arr[0] right? https://github.com/treeform/vmath/blob/5d7c5e411598cd5cf9071...

  Really I hope “duck typing” becomes more the norm rather than the OO stuff. I’m curious what the story in Swift on this topic is nowadays.
