what is the purpose of 'unimplemented' function in utils

[irfn]

I don't see usages of unimplemented function anywhere in the codebase.
src/main/clojure/clojure/core/matrix/utils.cljc
If there is no specific use, I would suggest removing this method.

The reason I ask is that this method adds a clojure.reflect dependency that I would like to avoid as I am trying to use core.matrix using https://github.com/borkdude/sci which is a lightweight interpreter.

Happy to take a PR to remove this. It was mostly useful during early development, when a lot of code paths needed to be completed.
