> I also don't agree with your characterization of Haskell, Rust and OCaml as being "high-barrier-to-entry" compared to Python. Personally, I find languages like Python much harder to work with given how arbitrary and detail oriented they are.

This is an interesting POV to be sure, but it should be made more practical and testable, by writing introductory resources for the average user that are targeted to these languages. Right now, the closest comparison to your prospective design for Yatima might actually be ATS, and I have trouble seeing ATS as figuring in a "Programming 101" tutorial.
